Answer:
c = -3
Step-by-step explanation:
Call the unknown c
c(x-3) +2x = -(x-5) +4
Distribute the negative sign
c(x-3) +2x = -x+5+4
Combine like terms
c(x-3) +2x = -x +9
Subtract 2x from each side
c(x-3) +2x-2x = -x-2x +9
c(x-3) = -3x+9
Factor a -3 from the right side
c(x-3) = -3(x-3)
Divide by (x-3)
c = -3
The right and left hand side need to be equal for there to be infinite solutions, so c = -3

Answer: 10 and -4
Step-by-step explanation:
3x - 2 Plug in 4 for x
