6x + 6 = 3x - 2 Bring 3x to the left and subtract: 6x - 3x = 3x 3x + 6 = -2 -2 - 6 = -8 -8 / 3 X = -8/3
6x - 12 = 3x + 12 Add twelve to both sides.6x - 12 + 12 = 3x + 12 + 12Simplify.6x = 3x + 24Subtract 3x from both sides.6x - 3x = 3x + 24 - 3xSimplify.3x = 24Divide both sides by 3.x = 8The answer is x = 8.
6x - 14 = 3x + 5Subtract 3x from each side: 3x - 14 = 5Add 14 to each side: 3x = 19Divide each side by 3: x = 19/3
2(3x + 4) + 5x - 2
6x + 4 = 3x + 19 3x + 4 = 19 3x = 15 x = 5 Check it. 30 + 4 = 15 + 19 It checks.
3x + 6y + 6x = 9x + 6y which can be factorised as 3(3x +2y)
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
5x^2 + 6x + 9 + (?) = -x^2 +3x + 3 (?) = -5x^2 -6x - 9 -x^2 +3x + 3 = -6x^2 -3x -6 Ans: -6x squared +3x -6
3x+50=6x+14 50-14=6x-3x 36=3x x=36 / 3 therefore x=12
3x + 7 = 6x - 2 Rearranging gives 6x - 3x = 7 + 2 3x = 9 x = 3
(6x - 5y) + (-3x - 4y) =6x - 5y - 3x - 4y =3x - 9y =3 (x - 3y)
6x-7 = 3x+5 6x = 3x+12 (subtracting -7) 3x=12 (subtracting 3x) x=4 (dividing by 3)
6x
9x + 3 - 6x - 2 = 3x + 1
3x + 6x - x= 8x
6x + 6 = 3x - 2 Bring 3x to the left and subtract: 6x - 3x = 3x 3x + 6 = -2 -2 - 6 = -8 -8 / 3 X = -8/3
3x-6x = -3
