Question

4. What value of x makes this equation true? ​

Answer 1

x = -30

Explanation:

Combine like terms. Subtract 0.1x from both sides; the result is 0.5x + 7 = -8. Next, subtract 7 from both sides, obtaining:

0.5x = -15

Dividing both sides by 0.5 results in x = -30

The equation is true for x = -30
