Question

-4x + 1 = -20 + 3x
4x - 1 = 6x + 7
5.(x+5)=45 +2x​

Answer 1

-4x + 1 = -20 + 3x

1 + 20 = 3x + 4x

21 = 7x

21/7 = x

3 = x

4x - 1 = 6x + 7

-1 -7 =  6x - 4x

-8 = 2x

-8/2 = x

-4  = x

5.(x+5) = 45 + 2x

5x + 25 = 45 + 2x

5x - 2x = 45 - 25

3x = 20

x = 20/3

Answer 2

-4x + 1 = -20 + 3x

-4x -3x = -20 - 1

-7x = -21

x=3

4x - 1 = 6x + 7

4x - 6x = 7 + 1

-2x = 8

x = -4

5 (x+5) = 45 + 2x

5x + 25 = 45 + 2x

5x - 2x = 45 - 25

3x = 20

x = 20/3
