Question

Don't give me the answer, just explain how I can solve it, please:
SOLVE: 13 - 3x = 4 (x - 2)

Answer 1

13 - 3x = 4 (x - 2)

distribute 4 through the parenthesis

13 - 3x = 4x - 8

move variables to the left side and change its sighn

13 - 3x - 4x = - 8
 
move constant to the right side and change its sign

-3x - 4x = - 8 - 13

collect like terms 

-7x = - 8 - 13

-3x - 4x = - 8 - 13

calculate the sum or difference 

-7x = - 21

divide both sides of the equation by - 7

x = 3
