#x=7#

Whenever you are solving for #x# or some variable, you have to isolate the variable.

Step 1: Combine Like Terms

Subtract 1x, then subtract 5. You get:

#2x=14#

Step 2: Solve (Isolate x, divide by 2)

#x=7#

REMEMBER: Whenever you want to "undo" an operation or get rid of something, you have to do the inverse or opposite operation.

Multiplication - Division
Addition - Subtraction
Exponents - [Square] Roots
