Question

Which equations have the same value as 3/5 (30x-15)=72 select 3

18x-15)=72
50x-25=72
3(6×3-3=72
X=4.5

Answer 1

x=4.5

Explanation:

Given the equation
`(3)/(5)(30x-15)=72`, we simplify as:

`(3)/(5)(30x-15)=72\\\\18x-9=72`

#We further simplify as multiples of 9(divide by 9 to solve for x):

`18x-9=72\\\\2x-1=8\\\\2x=9\\\\x=4.5`

Hence, from our simplification the equation has the same value as x=4.5
