8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
-8x + 4 = -4x; (-8+4)x = -4; x = 1.
8x+2y=4x=-y/4+0.5y=-4x+2
8x-5=23+4x 8x-5-4x=23+4x-4x 4x-5=23 4x-5+5=23+5 4x=28 4x/4=28/4 x=7
4x+5 = 8x+10But you are saying4x+5 = 8x+4If this were the case, 8x+10 = 8x+4, and so 10=4Thus there is no possible solution for X.====================================Honk! Go to your room.8x + 4 = 4x + 5Subtract 4x from each side:4x + 4 = 5Subtract 4 from each side:4x = 1Divide each side by 4:x =1/4Check:Left side: 8x + 4 = 8/4 + 4 = 2 + 4 = 6Right side: 4x + 5 = 4/4 + 5 = 1 + 5 = 66 = 6 yay!
