Hello Guest,
8(x+15)=12x
im confused on how to start it.
8(x + 15) = 12x
(8x + 8 * 15) = 12x
8x + 120 = 12x
(8x - 12x) + 120 = 12x -12x
-4x + 120 = 0
(120 - 120) -4x = -120
-4x = -120
\(\frac{-4x}{-4}=\frac{-120}{-4}\)
\(x = \frac{-120}{-4}\)
\(x = \frac{-30}{-1}\)
\(x = 30\)
So x = 30 is the right answer.
Hope that was helpful. ^^
