x=-3
x=-8
12x + 9 = 10x + 1 Subtract 10x from both sides: 2x + 9 = 1 Sutract 9 from both sides: 2x = - 8 Divide both sides by 2: x = -4
x + 10 = 18 18 - 10 = x 18 -10 = 8 x = 8
10x=80 divide each side by 10 to get x by itself 10/10x=1x 80/10=8 x=8
Subtracting gives: 10x = 80 so x = 8 and y = 5
8 = -6x x = -1.3333
5x+8 = 10x+35x-10x = 3-8-5x = -5x = 1 and by substituting the value of x into the equations y = 13
x=-3
12x - 8 = 10x + 42x = 12x = 6
10x + (8-x) = -19 10x + 8 = x - 19 10x = x - 27 9x = 27 x = 3
10x. 'coz x=? so just add 2 & 8.
7x + 8 = 10x - 2 ∴ 3x = 10 ∴ x = 10/3
x=-8
(x + 8)(x + 2)
Twenty-Five x2 + 10x = 8 x2 + 10x + 25 = 8 + 25 (x + 5)2 = 33
x = 6 Why? 10x + 8 = 68 Subtract 8 from both sides: 10x = 60 Divide both sides by 10: x = 6
