Use the diagram below to answer the following

Each month, a shopkeeper spends 5x + 14 dollars on rent and electricity. if he spends 3x−5 dollars on rent, how much does he spend on electricity? for which value(s) of x is the amount the shopkeeper spends on electricity less than $100? explain how you found the value(s).

Which steps could be part of the process in algebraically solving the system of equations, y+5x=x^2+10 and y=4x-10
