8(1+5x) + 5 = 13 + 5x
multiply the bracket by 8
(8)(1)=8
(8)(5x)=40x
8+40x+5=13+5x
8+5+40x=13+5x
13+40x=13+5x
move 5x to the other side
sign changes from +5x to -5x
13+40x-5x=13+5x-5x ( combine like terms)
13+35x=13
move 13 to the right side
13-13+35x=13-13
35x=0
divide both sides by 35 to get x by itself
35x/35=0/35
Answer:
x=0
