10x-2x =8x-527
10x=x 9x=0 x=0
11x = 10x-19 Subtact 10x fromboth sides:- x = -19
10x
10x+7=(-3) 10x=(-10) x=(-1)ans
10x - 3 = 17 Add 3 to both sides: 10x = 20 Divide both sides by 10: x = 2
15x-20y= 7 5y-3 +10x
12x - 6 = 10x +2 12x - 10x = 2 + 6 2x = 8 x = 4
well you divide by ten that's it the answer is 0.33333
0.9
Given: x2 + 10x - 16 Let: x2 + 10x - 16 = 0 x2 + 10x - 16 = 0 ∴ x2 + 10x + 25 = 16 + 25 ∴ (x + 5)2 = 41 ∴ x = -5 ± √41 ∴ x2 + 10x - 16 = (x + 5 + √41)(x + 5 - √41)
x=-8
