1) expand
-2+16=x+28
2) add 2x to both sides
16=x+28+2x
3) simplify x+28+2x to 3x+28
16=3x+28
4) subtract 28 from both sides
16-28=3x
5) simplify 16-28 to -12
-12=3x
6) divide both sides by 3
-12/3=x
7) simplify 12/3 to 4
-4=x
8) switch sides
x=-4
-2+16=x+28
2) add 2x to both sides
16=x+28+2x
3) simplify x+28+2x to 3x+28
16=3x+28
4) subtract 28 from both sides
16-28=3x
5) simplify 16-28 to -12
-12=3x
6) divide both sides by 3
-12/3=x
7) simplify 12/3 to 4
-4=x
8) switch sides
x=-4
