Right, 3x-4x+9x-x1. 3x - x = 2x2. 9x-4x = 5x- 2x +5x = 7x
9x = 4x + 45 5x = 45x = 9
4x+7=9x+7 -5x=0 x=0
9x + 8 = 4x + 23Subtract 8 from both sides9x = 4x + 15Subtract 4x from both sides5x = 15Divide both sides by 5x = 3
4x + 55 = 9x + 10 55 = 5x + 10 45 = 5x x = 9
Right, 3x-4x+9x-x1. 3x - x = 2x2. 9x-4x = 5x- 2x +5x = 7x
x+5+3x-7+9x+3-4x Collect like terms: 9x+1
9x = 4x + 45 5x = 45x = 9
4x+7=9x+7 -5x=0 x=0
9x + 8 = 4x + 23Subtract 8 from both sides9x = 4x + 15Subtract 4x from both sides5x = 15Divide both sides by 5x = 3

9x2+9x-12 All I can do is simplify this. I can't solve it unless turn this expression into an equation.
i thinking this answer should be -20
x=9
In this case you just add them together to make 9x.
4x+3=9x-4+4 +44x+7=9x-4x -4x7=5x-------57/5=1.41.4=x
9x+3-25 = 4x-2 5x = 20 x = 4
