5x - 5 = 3x - 9 add 5 to both sides: 5x =3x -4 subtract 3x from both sides: 2x = -4 Divide both sides by 2: x = -2
2x+3x-2=0=5x=0+2=5x=2=5x_5=2_5=x=0.4
3x + 2x = 5x
For 5x+y=1, you would subtract 5x from each side, so you would get y=1-5x For 3x+2y=2, you would subtract 3x from each side, and then divide by 2. 2y=2-3x y=1-(3/2)x
3x + 7 = 5x - 2Subtract 3x from each side:7 = 2x - 2Add 2 to each side:9 = 2xDivide each side by 2:x = 4.5
5x-2 = 3x-6 5x = 3x - 6 +2 5x = 3x - 4 5x - 3x = -4 2x = -4 x = -2
5x+2 = 3x-6 5x-3x = -6-2 2x = -8 x = -4

5x - 5 = 3x - 9 add 5 to both sides: 5x =3x -4 subtract 3x from both sides: 2x = -4 Divide both sides by 2: x = -2
2x+3x-2=0=5x=0+2=5x=2=5x_5=2_5=x=0.4
3x + 2x = 5x
5x+8x+3x-2x = 14x
For 5x+y=1, you would subtract 5x from each side, so you would get y=1-5x For 3x+2y=2, you would subtract 3x from each side, and then divide by 2. 2y=2-3x y=1-(3/2)x
3x + 7 = 5x - 2Subtract 3x from each side:7 = 2x - 2Add 2 to each side:9 = 2xDivide each side by 2:x = 4.5

3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
3x^2 + 5x - 8 = 0 + 8 + 8 3x^2 + 5x = 0 8x ^2 = 0
