Expression: x+10+5x Solve: x+5x=6x Answer: 6x+10
6x + 3 = -7 -5x 6x + 5x = -7 -3 11x = -10 x = -10/11
4x-3+2x-x = 10 Collect the like terms; 5x-3 = 10 5x = 13 x = 13/5
5x+2=x+10 5x-x=10-2 4x=8 x=2

Expression: x+10+5x Solve: x+5x=6x Answer: 6x+10
x=35
5x+7 = 2x-3 5x-2x = -3-7 3x = -10 x = -10/3
6x + 3 = -7 -5x 6x + 5x = -7 -3 11x = -10 x = -10/11
3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
4x-3+2x-x = 10 Collect the like terms; 5x-3 = 10 5x = 13 x = 13/5
5x+2=x+10 5x-x=10-2 4x=8 x=2
5x + (3y-x) + (10-2y) = 5x + 3y - x + 10 -2y = 5x - x + 3y - 2y + 10 = 4x + y +10

5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
3x-4=5x+6 gives: 2x=-10 which gives x=-5
3x + x + 10 + x = 5x + 10
