3(-3x - 1) - 9 = 5(x - 4)
Use the Distributive Property
-9x - 3 - 9 = 5x - 20
Simplify
-9x - 12 = 5x - 20
Add 9x to both sides
-12 = 14x - 20
Add 20 to both sides
8 = 14x
Divide by 14 on both sides
0.5714285714285714 = x
I would round
x = about 0.6
Solve for x:
3 (-1-3 x)-9 = -5 (x-4)
3 (-1-3 x) = -3-9 x:
-3-9 x-9 = -5 (x-4)
Add like terms. -9-3 = -12:
Answer: |
| -12-9 x = -5 (x-4) x=-8
