Yes. but if it has a negative sign in the front of it it is below sea level.
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
276 - 35d
276 = total pages
35 = pages read per day
35D = number of pages she has read during D days
Look at the solution ( again me)
