Explications étape par étape

8y-2(3y+1)=7y

8y-6y-2=7y

2y-2=7y

-2=7y-2y

-2=5y

y=-0.4

Bonsoir,

8y - 2(3y + 1) = 7y

8y -2 x 3y + -2 x 1 = 7y

8y - 6y + (-2) = 7y

2y + (-2) = 7y

2y + (-2) + 2 = 7y + 2

2y = 7y + 2

2y - 7y = 7y - 7y + 2

-5y = 2

5y = -2

5y/5 = -2/5

y = -0,4

Bonne journée et surtout, prends bien soin de toi ;)
