Algebraic Equations Practice Quiz

By solving the equation 6x - 30 = 0, we can isolate the variable x. Adding 30 to both sides of the equation gives us 6x = 30. Then, dividing both sides by 6, we get x = 5. Therefore, the correct answer is x = 5.

To solve the equation 3x - 20 = 1, we need to isolate the variable x. First, we add 20 to both sides of the equation to get 3x = 21. Then, we divide both sides by 3 to find that x = 7. Therefore, the correct answer is x = 7.

By subtracting 30 from both sides of the equation, we get 6x = 30. Then, by dividing both sides by 6, we find that x = 5.

To solve the equation 8x + 100 = 180, we need to isolate the variable x. First, we subtract 100 from both sides of the equation, which gives us 8x = 80. Then, we divide both sides of the equation by 8 to solve for x. This yields x = 10. Therefore, the correct answer is x = 10.

To evaluate the expression 6w - 2a, we substitute the given values of w = 4 and a = 2 into the expression. Therefore, we have 6(4) - 2(2) = 24 - 4 = 20. Hence, the correct answer is 20.

To solve the equation 8x - 15 = 25, we need to isolate the variable x. First, we add 15 to both sides of the equation to get 8x = 40. Then, we divide both sides by 8 to find that x = 5.

The inequality y - 16

To solve the equation y/-8 + 2 = -100, we need to isolate the variable y. First, we subtract 2 from both sides of the equation to get y/-8 = -102. Then, we multiply both sides of the equation by -8 to eliminate the fraction and obtain y = 816. Therefore, the correct answer is y = 816.

To solve the equation, we need to isolate the variable y. First, we can multiply both sides of the equation by -3 to get rid of the fraction. This gives us y + (-6) = 39. Simplifying further, we have y - 6 = 39. To isolate y, we can add 6 to both sides of the equation, resulting in y = 45. Therefore, the correct answer is y = 45.
