3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
-3x+2 = 2x-8 8+2 = 2x+3x 10 = 5x x = 2
According to my calculations, yes. 2x+8=3x+11 -8 2x=3x+3 -2x 0=x+3 -3 -3=x
2x+9 = 49-3x 2x+3x = 49-9 5x = 40 x = 8
3x + 4 = 8 + 2xSubtract 4 from each side:3x = 4 + 2xSubtract 2x from each side:x = 4
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
-3x+2 = 2x-8 8+2 = 2x+3x 10 = 5x x = 2
According to my calculations, yes. 2x+8=3x+11 -8 2x=3x+3 -2x 0=x+3 -3 -3=x
3x + 2x = 40 5x = 40 x = 8
3x+5 = 2x+13 3x-2x = 13-5 x = 8
2x+9 = 49-3x 2x+3x = 49-9 5x = 40 x = 8
x-3x = -8 -2x = -8 x = 4
3x + 4 = 8 + 2xSubtract 4 from each side:3x = 4 + 2xSubtract 2x from each side:x = 4
2x + 8 = 3x - 4 Subtract 2x from both sides: 8 = x - 4 Add 4 to both sides: 12 = x
x=12
If x equals 8, then 3x equals 24. 24-x would equal 16.
3x2 + 2x - 8 = 0 is a quadratic equation.
