5x+10-5y-3x+1=0 <--You start with this. Then move the 10 and 1 to the other side by subtracting them.
5x-5y-3x=-11<--Next combine the x's
2x-3y=-11<--This is the simplified answer.
3x + 7 = 5x + 13 3x - 5x = 13 - 7 -2x = 6 -x = 3 x = -3
3x + x + 10 + x = 5x + 10
5x + 4
5x - 10 = 3x + 2 5x - 3x = 2 + 10 2x = 12 x = 12/2 x = 6
122-5x = 3x+10 122-10 = 3x+5x 112 = 8x 112/8 = x x = 14
3x - 5x + x = -x
3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
6-3x = 5x-10x+10 6-3x = -5x+10 -3x+5x = 10-6 2x = 4 x = 2
3x + 7 = 5x + 13 3x - 5x = 13 - 7 -2x = 6 -x = 3 x = -3
3x + x + 10 + x = 5x + 10
5x + 4
5x - 10 = 3x + 2 5x - 3x = 2 + 10 2x = 12 x = 12/2 x = 6
122-5x = 3x+10 122-10 = 3x+5x 112 = 8x 112/8 = x x = 14
3x + 9 = 5x - 43x +13 = 5x13 = 2x13/2 = xso x = 6.5
Depending on how the problem is written. 2x + 3 - 5x + 10 -3x + 13 ■ Or... 2x + 3 - (5x + 10) -3x - 7 ■ I think you want the second answer.
k = 7 x^4 - 5x^3 + 7x^2 + 3x - 10 = (x + 1)(x - 2)(x^2 - 4x + 5)
5x - 2x = 3x
