3x+8=15
move + 8 to the other side
sign changes from + 8 to - 8
3x+8-8 = 15-8
3x = 15-8
3x = 7
divide both sides by 3 to get x by itself
3x/3 = 7/3
answer:
7/3 or 2 1/3

Misha solves the equation 3 x minus 2 (x + 3) = 4 (x minus 2) minus 7 by applying the distributive property to each side of the equation. The result is 3 x minus 2 x minus 6 = 4 x minus 8 minus 7. Misha then wants to combine like terms.
