Answer: x = -20
=====================================
Work Shown:
(x+4)/(-6) = 8/3
3(x+4) = -6*8 ... cross multiply
3x+12 = -48
3x = -48-12 ... subtract 12 from both sides
3x = -60
x = -60/3 ... divide both sides by 3
x = -20
---------------------
Check:
(x+4)/(-6) = 8/3
(-20+4)/(-6) = 8/3 .... replace every x with -20
(-16)/(-6) = 8/3
(-2*8)/(-2*3) = 8/3
8/3 = 8/3 ... the '2's cancel when dividing
We get the same number on both sides, so this confirms the solution.
