3x - 2x + 3 - 5x = 11
- 4x + 3 = 11
- 4x + 3 - 3 = 11 - 3
- 4x = 8
- 4x/- 4 = 8/- 4
x - 8/- 4
x = - 2
The answer is x = - 2
Insert the x value into the equation
- - - - - - - - - - - - - - - - -- - - - - -
3x - 2x + 3 - 5x = 11
3(- 2) - 2(- 2) + 3 - 5(- 2) = 11
- 6 - (- 4) + 3 - (- 10) = 11
-6 + 4 + 3 + 10 = 11
- 6 + 17 = 11
11 = 11

First subtract 3 from each side
3X-2X-5X=(11-3)
Then do math
-4X=8
Then divide by (-4)
(-4X / -4)= (8 / -4)
ANSWER
X = -2
The negative fours cancel out to leave X alone

add all the terms with "x" together
-4x+3=11
subtract 3 from both sides to get
-4x=8
divide both sides by -4 to get x by itself
x=-2
