Solve for x showing all work. You will not get credit for your answer if you do not show your work. 4(x - 4) + 14 = 2(8 - 2x) +

4x-16+14=16-4x+6.
4x-16+14-16+4x-6=0(bring all values at one side)
4x+4x+14-16-16-6=0(arrange)
8x-24=0(solve)
8x=24(bring 8 on right hand side so x is alone)
X=24/8(solve)
X=3
