Answer 1

I don't understand

Answer 2

forget that then.. here is a more detailed explanation..

Answer 3

ok

Answer 4

Simplifying
3x + -7 = 5x + 19

Reorder the terms:
-7 + 3x = 5x + 19

Reorder the terms:
-7 + 3x = 19 + 5x

Solving
-7 + 3x = 19 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.
-7 + 3x + -5x = 19 + 5x + -5x

Combine like terms: 3x + -5x = -2x
-7 + -2x = 19 + 5x + -5x

Combine like terms: 5x + -5x = 0
-7 + -2x = 19 + 0
-7 + -2x = 19

Add '7' to each side of the equation.
-7 + 7 + -2x = 19 + 7

Combine like terms: -7 + 7 = 0
0 + -2x = 19 + 7
-2x = 19 + 7

Combine like terms: 19 + 7 = 26
-2x = 26

Divide each side by '-2'.
x = -13

Simplifying
x = -13
