Answer:
x=6
Step-by-step explanation:
first, remember to simplify each side of the equation
so, 9=x+3, because -5+8=3
9=x+3
remember, you must isolate x by reversing the operation that is done on x
so, right now 3 is being added to x.
So, to reverse, you have to subtract 3, but remember, what is done to one side must be done to both
9=x+3
-3 -3
6=x
