-2x+14=20 -2x=20-14 -2x=6 -2x/-2=6/-2 x=-3
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
8x + 2 = 6x + 10 Subtract 6x from both sides: 2x + 2 = 10 Subtract 2 from both sides: 2x = 8 Divide by 2: x = 4 x = 4
2x+1 = 9 2x = 9-1 2x = 8 x = 4
3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3
As you've written it, it can't be solved. I'll assume you mean -2x plus 8=2. -2x=-6. x=3.
When using substitution the answer to y0.5x plus 2 -y-2x plus 4 is y = -2 (x-1.
If we assume that it equals zero and you wish to solve for x, then the answer is:-x2 + 2x - 3 = 0x2 - 2x + 3 = 0x2 -2x + 1 = -2(x - 1)2 = -2x - 1 = ± √(-2)x = 1 ± i√2
If: x+1+2x = 1x+5 Then: x = 2
2x + 1 = 9 2x = 9 - 1 2x = 8 2x/2 = 8/2 x=4
2x+3 = 7 2x = 7-3 2x = 4 x = 2
3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6
3x-2 = 2x+3 3x-2x = 3+2 x = 5
4x+2=2x-102x=-12 x=-6
2x+8 = 6 2x = 6-8 2x = -2 x = -1
3x + 2x = 5x
2x + 5 - 5 = 2x. You can not solve for x because this is not an equation.
