22+2x = 37+6+x 2x-x = 37+6-22 x = 21

3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6

8x-7 plus 2x equals 6 plus 5x plus 2?

2x-3=9 so 2x=12 and x=6

4x+6-2x=14 First you combine the like terms, so you would get 2x+6=14. Then subtract both sides by 6 2x=8 Finally divide both sides by 2 x=4.

22+2x = 37+6+x 2x-x = 37+6-22 x = 21

2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9

2x + 7 = 1 Therefore, 2x = -6 x = -6/2 x = -3

X=6

12 = 2x + 6 subtract 6 from both sides 6 = 2x divide both sides by 2 3 = x

4x=-10 x=-2.5

Yes, they are. If you solve 2x + 7y = 6 for y, you get y = (-2x + 6) / 7. If you solve 7y + 2x + 6 = 0 for y, you get y = (-2x - 6) / 7. As you can see, both equations have the same slope. Therefore they are parallel. You can punch those equations into a graphing calculator and visually verify that they are indeed parallel.

To solve this equation we have to isolate and solve for x. So: 2x-6= x+5 +6 +6 2x = x+11 -x -x x = 11 So x=11.

this can not be solved un less with another equation

Yes and it works out that x = 3 and y = 4

3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6

x=1
