10 (y+2) - y=2 (9y-8) i need to know how to solve it

10 (y+2) - y=2 (9y-8)

Mutiply the first bracket by 10

Mutiply the second bracket by 2

(10) (y) (10) (2) = 10y+20

(2) (9y) (2) (-8) = 18y-16

10y+20-y = 18y-16

10y-y+20 = 18y-16

9y+20 = 18y-16

move 18y to the other side

sign changes from + 18y to - 18y

9y-18y+20 = 18y-18y-16

-9y+20 = - 16

move + 20 to the other side

sign changes from + 20 to - 20

-9y+20-20=-16-20

-9y = - 36

divide by - 9

-9y/-9 = - 36/-9

y = 4

Answer: y = 4
