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.
[tex]-\frac{8.61}{86.1}[/tex] = x
6. Simply [tex]-\frac{8.61}{86.1}[/tex] to 10
−10 = x
7. Flip it.
x = −10
