%28%28x%2B2%29%2F3%29+=+%288%2F15%29 [Cross-multiply]
(x+2)(15) = (3)(8) [Simplify]
15x+30 = 24 [Solve for x]
15x+30 - 30 = 24 - 30
15x = -6
15x/15 = -6/15
x=-6/15
.
Check by plugging (x=-6/15) back into the original equation.
%28%28x%2B2%29%2F3%29+=+%288%2F15%29
%28%28%28-6%2F15%29%2B2%29%2F3%29+=+%288%2F15%29%29
%28%28%28%28-6%2B30%29%2F15%29%29%2F3%29+=+%288%2F15%29%29
