x*x - 8x +16 = 0 x*x = 8x + 16 x - 16 = _/8x x_/-4 = 2 x = 2
8x + 16 = 6x -> 2x + 16 = 0 -> 2x = -16 -> x = -8
8x + 9.16 = 4x + 16 8x - 4x = 16 - 9.16 4x = 6.84 x= 1.71
We don't see a conflict. 'x' is 2, and there shouldn't be much debate about that.
You add 8x to each side. This gives you 5 = 16. Since this has no solution, the original equation doesn't have any solution, either.

8 is the coefficient. A coefficient is the number in front of a variable.
8x + 9.16 = 4x + 16 8x - 4x = 16 - 9.16 4x = 6.84 x= 1.71

If 8x + 4y = 16, then y = - 2x + 4 Thus the slope is -2 and the intercept is 4.
L2 math.
16 + 2x = 10 + 8x 2x - 8x = 10 - 16 -6x = -6 x = 1 Check: 16 + 2(1) = 10 + 8(1) 18 = 18
8x = 16 is NOT an 'Inequality#'. However, 8x > 16 is an inequality as is 8x > 16 . NB Treat inequalities as an 'equals'. except for negative numbers or fractions. Hence 8x > 16 Divide both sides by '8' x > 2 Similarly 8x < 16 x < 2
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
