10x 2x divide 2x equals?
10x - 3y + 2x - 4y =(10x + 2x) + (-3y - 4y) =12x - 7y
10x-2x =8x-527
2x-3 = 21+10x 2x-10x = 21+3 -8x = 24 x = -3
2x + 10x - 6 = 12x - 6
2x-3=10x+21 2x-3-2x=10x+21-2x -3=8x+21 -3-21=8x+21-21 -24=8x -3=x
10x
22
10x+2x-3y-4y=12x-7y
6x2 + 10x = 2x*(3x + 5)
2x + (10x - 4) = 20 2x + 10x - 4 = 20 12x - 4 = 20 12x = 24 x = 2
The solution is 1/2 or 0.5. This is how: 2x+1=7-10x 2x=6-10x 12x=6 x=1/2
