\Delta =1225-4\times 57\times 1
Consider the first equation. Calculate 35 to the power of 2 and get 1225.
\Delta =1225-228\times 1
Multiply 4 and 57 to get 228.
\Delta =1225-228
Multiply 228 and 1 to get 228.
\Delta =997
Subtract 228 from 1225 to get 997.
\Delta =997 a=7 b=7
The system is now solved.
