7 + 2x = 11 + x
Combine like terms by subtracting the 7 from both sides.
7 + 2x = 11 + x
-7 -7
This will leave you with 2x = 4 + x. Again, combine like terms, this time subtracting the x from both sides.
2x = 4 + x
-x -x
This will now leave you with 1x = 4. 1x and x are equivalent, so you can just forget about the one, leaving you with x = 4 as your final answer.
Hope this helped.
2x+a=p 2x=p-a x=.5p-.5a
2x + 3 + 3x = x + 11 5x + 3 = x + 11 4x + 3 = 11 4x = 8 x = (8/4) x = 2
2x-11
2x + 3y = 11Subract 2x from each side:3y = 11 - 2xDivide both sides by 3:y = 11/3 - (2/3)x

2x+3 = -11 2x = -11-3 2x = -14 x = -7
-2x+13y=11 13y=2x+11 y=2x/13 + 11/13
4x + 3 = -3 + 2x + 14 2x + 3 = -3 +14 2x + 3 = 11 2x = 8 x=4
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.

y= -2x
2x + 3 + 3x = x + 11 5x + 3 = x + 11 4x + 3 = 11 4x = 8 x = (8/4) x = 2

If 2x + 5 = 11, then 11 - 5 = 2x 6 = 2x 3 = x
x=5.54x+1= 2x+12-1 -14x=2x+11-2x -2x2x=11/2 /2x=5.5
x + 2x = 33 3x = 33 3x/3 = 33/3 x = 11
2x - 5 = 11 2x = 11 + 5 2x = 16 2x /2 = 16 /2 x = 8
