If there are no parenthesis around the equation:
Find which number that, when divided by 8 and added by 3 = 10.
Subtract 3 from both sides yielding: 8/y=7
Multiply both sides by "y": 8=7y which we'll turn around to make it easier: 7y=8
Divide both sides by 7 yielding: y=8/7 which can be simplified to 1 and 1/7, or 1.1429...
So, the answer is 8/7 simplified however the teacher desires.
