6*(b-3)=10-2*(b+2) и 83+5*(у-3)=3*(8у-9)

6*(b-3)=10-2*(b+2)
6b-18=10-2b-4
6b+2b=18+10-4
8b=24
b=24/8
b=3
83+5*(у-3)=3*(8у-9)
83+5y-15=24y-27
5y-24y=-83+15-27
-19y=-95
y=-95/-19
y=5

6 * (b - 3) = 10 - 2 * (b + 2)
6b - 18 = 10 - 2b - 4
6b + 2b = 10 + 18 - 4
8b = 28 - 4
8b = 24
b = 24 : 8
b = 3
ответ: b = 3
