Question

Реши уравнение 83+5*(y-3)=3*(8y-9)

Answer 1

83+5*(y-3)=3*(8y-9)
83+5y-15=24y-27
5y-24y=-83+15-27
-19y=-95
y=-95:(-19)
y=5

Answer 2

83 + 5 · (y-3) = 3 · (8y - 9)
83 + 5y - 15 = 24y - 27
5y - 24y= -83 + 15 - 27
-19y = -95
19y = 95
y= 95 : 19
y= 5

проверим

83 + 5 · (5 - 3) = 3 · (8 · 5 - 9)
83 + 5 · 2 = 3 · (40 - 9)
83 + 10 = 3 · 31
93 = 93
