5x-2x-3x+4x = (5-2-3+4)x = 4x
-2x-3.
6-3x = 5x-10x+10 6-3x = -5x+10 -3x+5x = 10-6 2x = 4 x = 2
x=1 2/3 How?: 2x-4+3 = 5x-6 2x-1 = 5x-6 2x-1+1 = 5x-6+1 2x = 5x-5 2x-5x = 5x-5x-5 -3x = -5 -3x/-3 = -5/-3 x = 5/3 x = 1 2/3
(3x + 4)(2x - 1) = 0 3x = -4 x = -4/3 2x = 1 x = 1/2 x = 1/2, -4/3
3x + 2x = 5x. 5x= (-4) X = (-4)/5 x= -0.8
5x-2x-3x+4x = (5-2-3+4)x = 4x
It is 5x - 4
5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
3x + 4 = 5x - 6 -3x -3x 4 = 2x - 6 +6 +6 10 = 2x 5 = x
5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4
3x+5=4-2x+6 5x=4-1 5x=3 x=3/5
-2x-3.
2(3x + 4) + 5x - 2
-2x+20 = 3x 20 = 3x+2x 20 = 5x 4 = x So x = 4
3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
5x + 4 = 3x - 2Subtract 4 from both sides:5x = 3x - 6Subtract 2x from both sides:2x = 6Divide both sides by 2:x = -3
