Answer:
x = -8
Step-by-step explanation:
-4(2x+3) = 2x+6-(8x+2)
Distribute
-8x-12= 2x+6-8x-2
Combine like terms
-8x-12 = -6x+4
Add 8x to each side
-8x-12 +8x = -6x+4+8x
-12 = 2x+4
Subtract 4 from each side
-12-4 = 2x+4-4
-16 = 2x
Divide each side by 2
-16/2 = 2x/2
-8 =x
Answer:
Janet has coins worth 252.5, 101, and 50.5.
Step-by-step explanation:
