4x+3(2-x)=8-2xsolve for x, give a reason for each step
Accepted Solution
A:
4x+3(2-x)=8-2xMultiply the bracket by 3(3)(2)=6x(3)(-x)=-3x4x+6-3x=8-2x4x-3x+6=8-2x ( combine like terms)x+6=8-2xMove -2x to the other side. Sign changes from -2x to +2x.x+2x+6=8-2x+2xx+2x+6=83x+6=8Move +6 to the other side. Sign changes from +6 to -6.3x+6-6=8-63x=2Divide by 3 for both sides to get x by itself.3x/3=2/3Cross out 3 and 3, divide by 3 and then becomes 1*1*x=xAnswer: 2/3
