Answer 2

4x = 76
Where x is how many awnsers he got correct and 4 how many points each correct question awnsered.

Now you just have to isolate x by dividing both sides of the equation by 4

4x/4 = 76/4
x = 19

So he got 19 questions right and 10 awnsers wrong. In total there were 29 questions on his test
