Answer: x = 19
Step-by-step explanation:
5(-12x+3) + 6(10x + 7) = 9 - x + 3x + 10 Distribute on the left side
-60x + 15 + 60x + 42 = 9 + 2x + 10 combine like terms on the left side
57 = 9 + 2x + 10 Now combine like terms on the right side
57 = 2x + 19 Subtract 19 from both sides
-19 -19
38 = 2x Divide both sides by 2
x = 19
3b+2(b-1) = 8
3b+2b-2 = 8
5b = 8+2
5b = 10
b = 2
If y=12 when x=6, then y=36 when x=18 by the equation y=2x.
