just distribute, then combine like terms: if it helps break it down: 4(7x),4(-1)=3(2x),3(1)=-4(x),-4(6) so then you have: 28x-4=6x+3-4x-24, then just combine like terms, you goal is to isolate the variable

7(x-2)+3(x+2)=5(x-6) 7x-14+3x+6=5x-30 -distribute 10x-14+6=5x-30 -combine like terms 10x-8=5x-30 -get x's on 1 side 5x-8=-30 5x=-22 -isolate the x x=-22/5
