Answer by JBarnum(2146) (Show Source): You can put this solution on YOUR website!
83%=7/10 or 70% of your grade
x=3/10 or 30% of your grade
so 7/10+3/10=10/10
and since your looking for a 70% you set equation = to 70 because that is the average you are looking for.
the reason i multiply 83 by 7 is because the average of which is your given percentage, though your grades may be differentbut the result is same and for this purpose its just easier to calculate.

for a 70%
