If 3x + 3 = 2x + 6 then 3x - 2x = 6 - 3 x = 3
1
x= -3
2x+3=9x 3=9x-2x 3=7x x=3/7
3x2 + 2x + 3 + x2 + x + 1 = 4x 2+ 3x + 4
2x = x+3 2x-x = 3 x = 3
(2x + 3)(x + 1 ) = 2x^2 +5x +3
x+3(x+1)=2x x + 3x + 3 = 2x 2x + 3 = 0 2x = -3 or x = -1.5
2x + 3 = x 2x + 3 - 3 = x - 3 2x = x - 3 2x - x = x - 3 - x x = -3
x - 2x + 3 = 3 - x
x + 3 + 2x = x + 3 subtract x + 3 to both sides 2x = 0 divide by 2 to both sides x = 0
6x with 3 over the x, because that is how many x's there are.
2x=x+3=x=3
2x = 4x + 3 -2x = 3 x = -3 / 2
2x-3 = x+5 2x-x = 8 x = 8
2x-3=x+2 2x-x=2+3 x=5
2x+2=x+5 x=3
