3x + 4x -6x = 17
x = ?
Correct Answer
A. 17
Explanation
The equation is given as 3x + 4x - 6x = 17. Combining like terms, we get x = 17.
2.
33 = 4x + 13
x = ?
Correct Answer
B. 5
Explanation
The equation 33 = 4x + 13 can be solved by isolating the variable x. By subtracting 13 from both sides of the equation, we get 20 = 4x. Dividing both sides by 4, we find that x = 5.
3.
X +2x +3x +4x + 5x = 45
x = ?
Correct Answer
A. 3
Explanation
To solve the equation, we can combine like terms by adding up all the x terms on the left side of the equation. Adding x + 2x + 3x + 4x + 5x gives us 15x. So the equation becomes 15x = 45. To isolate x, we divide both sides of the equation by 15. This gives us x = 3. Therefore, the value of x that satisfies the equation is 3.

A + 2b +33 = 66 + 2b
a = ?
Correct Answer
B. 33
Explanation
In the given equation, we have a + 2b + 33 = 66 + 2b. By subtracting 2b from both sides of the equation, we get a + 33 = 66. By subtracting 33 from both sides, we find that a = 33.

2•(c + 2c + 3c + 4c ) = 100
c = ?
Correct Answer
B. 5
Explanation
In the given equation, the expression inside the parentheses is simplified as 10c. Multiplying 2 by 10c gives 20c. The equation then becomes 20c = 100. Dividing both sides of the equation by 20 gives c = 5. Therefore, the correct answer is 5.

Cila formule eshte shkruar drejte. Shuma e tre nr natyrore te njepasnjeshem eshte 50 ?
Correct Answer
B. X + (x+1) + ( x+2) = 50
Explanation
The correct answer is "x + (x+1) + (x+2) = 50" because it represents the sum of three consecutive natural numbers. The first term is x, the second term is x+1, and the third term is x+2. Adding these three terms together gives a total of 50.
7.
x + ( x + 1 ) + ( x + 2 ) = 24
x = ?
Correct Answer
A. 7
Explanation
In the given equation, we need to find the value of x that satisfies the equation. By simplifying the equation, we can rewrite it as 3x + 3 = 24. Solving for x, we subtract 3 from both sides, giving us 3x = 21. Dividing both sides by 3, we find that x = 7. Therefore, the correct answer is 7.
8.
X + 3x +7x = 121
x =?
Correct Answer
B. 11
Explanation
In the given equation, we have the sum of three terms: x, 3x, and 7x, which equals 121. To find the value of x, we need to combine like terms, which gives us 11x = 121. To solve for x, we divide both sides of the equation by 11, resulting in x = 11. Therefore, the correct answer is 11.
9.
Nese x+2x=60 atehere 5•(x+2x) = ?
Correct Answer
A. 300
Explanation
The equation x + 2x = 60 can be simplified to 3x = 60. Solving for x, we find that x = 20. Substituting this value into the expression 5(x + 2x), we get 5(20 + 2(20)) = 5(20 + 40) = 5(60) = 300. Therefore, the answer is 300.

2x +5 = x + x + 3 + 2
Correct Answer
B. Identitet matematikore
Explanation
The given equation is 2x + 5 = x + x + 3 + 2. By simplifying both sides of the equation, we can combine like terms. On the left side, 2x can be simplified to 2x, and on the right side, x + x can be simplified to 2x. Similarly, 3 + 2 can be simplified to 5. Therefore, the equation can be rewritten as 2x + 5 = 2x + 5. This means that the equation is an identity, which means that it is true for all values of x.
