Answer:
x = 22
Step-by-step explanation:
x-10=12
add 10 to each side
x-10+10=12+10
x=22
To find the answer you must isolate x. So the first step would be to add 10 to each side (you must do the same thing to both sides). You would end up with x=22. You can replace x with 22 and solve to check your work.
