5x+10=11x-2 add 2 to each side
5x+12=11x subtract 5x from each side
12=6x divide by 6
2=x or
x=2

5x + 10 = 11x - 2 you add 2 to 10
so ..
5x + 12 = 11x now subtract 5x from 11x
12x = 6x divide 6 by 12
x= 2

5x + 10 = 11x - 2
I don't like negative coefficients, so I'll subtract 5x from both sides:
5x - 5x + 10 = 11x - 5x - 2
10 = 6x - 2
Swapping ends, I get
6x - 2 = 10
Adding 2 to both sides:
6x - 2 + 2 = 10 + 2
6x = 12
Finish up by dividing both sides by 6
6x/6 = 12/6
x = 2

Subtract 5x from both sides:
10 = 6x - 2
Add 2 to both sides:
12 = 6x
Divide both sides by 6:
x = 2
Double-check:
5(2) + 10 =? 11(2) - 2
10 + 10 =? 22 - 2
20 = 20 <-- check
So x = 2

*Our goal is solving for “x,” and we’ll make sure “x” is on the left side
First Step: subtract 11x from both sides
5x - 11x + 10 = 11x -11x – 2
-6x + 10 = -2
Second step: subtract 10 from both sides
-6x + 10 – 10 = -2 – 10
-6x = -12
Third step divide –6 by both sides
-6x/-6 = -12/-6
x = 2

5x+10=11x-2
5x - 11x = -2 -10
-6x = -12
x = 2
Solution: {x E R | x = 2}.

5x+10=11x-2 [EQUATION]
(+2) (+2) [balance the equation, combine like terms]
--------------
5x+12=11x
(-5x) (-5x) [continue combining like terms]
--------------
12=6x
(12/6) (6/6) [divide both sides by 6 to get x by it's self]
--------------
2=x [SOLUTION]
