x*x - 8x +16 = 0 x*x = 8x + 16 x - 16 = _/8x x_/-4 = 2 x = 2
3 - x = 8x = 3 - 8x = - 5
8x=7x-7 x=-7

5x-3=2-8x 5x-3+3=2-8x+3 5x=5-8x 5x+8x=5-8x+8x 13x=5 x=5/13
8x + 3 = 35 8x = 32 x = 4
2-8x=22 -8x=20 -x=2.5 x=-(2.5)
X=5

No.
x*x - 8x +16 = 0 x*x = 8x + 16 x - 16 = _/8x x_/-4 = 2 x = 2
8x = -104 Therefore, x = -104/8 x = -13
3 - x = 8x = 3 - 8x = - 5
8x=7x-7 x=-7
