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

Question

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

Answer 1

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

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

Answer 2

6*b-18=10-2*b-4
6*b+2*b=6+18
8*6=24
b=3
83+5*y-15=24*y-27
19*y=68+27
y=95:19
y=5
