Question

-12.11x - 10.5 = 75.6 - 3.5x

Answer 1

Answer:

x = −10

Step-by-step explanation:

1. Add 12.11x to both sides.

−10.5 = 75.6 − 3.5x + 12.11x

2. Simplify 75.6 - 3.5x + 12.11x to 75.6 + 8.61x.

−10.5 = 75.6 + 8.61x

3. Subtract 75.6 from both sides.

−10.5 − 75.6 = 8.61x

4. Simplify −10.5 −75.6  to −86.1.

−86.1 = 8.61x

5. Divide both sides by 8.61.

​​$-\frac{8.61}{86.1}$ = x

6. Simply $-\frac{8.61}{86.1}$ to 10

−10 = x

7. Flip it.

x = −10
