Question

Which equations have the same value of x as Three-fifths (30 x minus 15) = 72? Select three options.

18x - 15 = 72
50x - 25 = 72
18x - 9 = 72
3(6x - 3) = 72
x = 4.5

Answer 1

3/5(30x-15)=72
3/5(30x•3/5(3/5•-15)=72
18x-9=72
+9 +9
(1/18)18x=80(1/18)
X=80*1/18=4.44
X=4.44

Answer 2

18x-9=72

Explanation:

3/5(30x-15)=72

3/5*30x-3/5*15=72

18x-9=72

hope this helps! comment any questions <3
