3(x - 5x) + 2(xy + 8x) + (-8xy)
First, simplify x - 5x to get -4x. / Your problem should look like: 3 × -4x + 2(xy + 8x) + -8xy
Second, simplify 3 × -4x to -3 × 4x / Your problem should look like: -3 × 4x + 2(xy + 8x) + -8xy
Third, simplify 3 × 4x to get 12x. / Your problem should look like: -12x + 2(xy + 8x) - 8xy
Fourth, expand your equation. / Your problem should look like: -12x + 2xy + 16x - 8xy
Fifth, gather the like terms. / Your problem should look like: (-12x + 16x) + (2xy - 8xy)
Sixth, simplify -12x + 16x to get 4x and 2xy - 8xy to get 6xy. / Your problem should look like: 4x - 6xy
Answer: 4x - 6xy
