4x-3+2x=8x-3-x

=4x+2x=8x-x

=6x=7x

=6x+(-7x)=7x+(-7x)

=x=0

=4x+2x=8x-x

=6x=7x

=6x+(-7x)=7x+(-7x)

=x=0

Simplify the following expression using PEMDAS 4(5 + 3x) – 5( -4 – 2x) **Weegy:** 4(5 + 3x) - 5(-4 - 2x) = 20 + 12x - (-20 - 10x) = 20 + 12x + 20 + 10x, we then group like terms together: 40 + 22x. Your final answer is 40 + 22x (More)

9(x - 2) = 8(x + 1)

9x - 18 = 8x + 8

9x - 8x = 8 + 18

x = 26

9x - 18 = 8x + 8

9x - 8x = 8 + 18

x = 26

-3(x + 2) = 18

-3x - 6 = 18

-3x = 18 + 6 = 24

x = 24/-3 = -8

-3x - 6 = 18

-3x = 18 + 6 = 24

x = 24/-3 = -8

5x + 4 = 34

5x = 34 - 4 = 30

x = 30/5 = 6

5x = 34 - 4 = 30

x = 30/5 = 6
