Answer:

x=10

Explanation:

5(2x+6)=-4(-5 -2x) + 3x

$\longrightarrow$ Use the distributive property to multiply 5 by 2x+6, and -4 by -5 - 2x.

10x+30=20+8x+3x

$\longrightarrow$ Combin 5x and 2x to get 11x:-

10x+30=20+11x

$\longrightarrow$ Subtract 11x from both sides:-

10x+30-11x=20

$\longrightarrow$ Combine 10x and -11x to get -x:-

-x+30=20

$\longrightarrow$ Subtract 30 from both sides:-

x=20-30

$\longrightarrow$ Subtract 30 from 20 to get -10:-

-x=-10

$\longrightarrow$ Multiply both sides by -1:-

x=10
