The equations have the same value of x are 3(30x - 15) = 360, (30x - 15) = 120 and 30x = 135
The equation is given as
Three-fifths (30 x minus 15) = 72
Rewrite properly as:
3/5(30x - 15) = 72
Multiply through the equation by 5
So, we have:
3(30x - 15) = 360 --- the first equation
Divide both sides of the equation by 3
So, we have:
(30x - 15) = 120 --- the second equation
Add 15 to both sides of the equation
So, we have:
30x = 135 --- the third equation
Hence, the equations have the same value of x are 3(30x - 15) = 360, (30x - 15) = 120 and 30x = 135
