Answer:
Subtract
x=12
Step-by-step explanation:
To solve equations, we have to get x by itself. To do this, we must preform the opposite of what is being done to the equation. Keep in mind, everything must be done to both sides of the equation.
x+15=27
15 is being added onto x. The opposite of addition is subtraction. Therefore, we must subtract 15 from both sides
x+15-15=27-15
x=27-15
x=12
