Question 79088: I made a mistake with the original question, here is the correction;
The formula G=~(2.5x+357) and L=7.43~(x-115) model the loan amounts, in billions of dollars, to college students for grants, G, and loans, L, x years after 1970. In which year was the amount from loans the same as the amount from grants? Please show your work.

You can put this solution on YOUR website! The formula G=~(2.5x+357) and L=7.43~(x-115) model the loan amounts, in billions of dollars, to college students for grants, G, and loans, L, x years after 1970. In which year was the amount from loans the same as the amount from grants? Please show your work.
----------
Loans will equal grants when G = L:
---------
EQUATION:
2.5x+357=7.43-(x-115)
2.5x+357=7.43-x+115
3.5x=7.43+115-357
3.5x=-234.57
x=-67.02
1970-67.02=1902
---------
I doubt that this is the correct answer but
it is the answer for what you have posted.
--------
Check your problem again; did you post it correctly?
Cheers
