y=3\times 1+5-0.04\times 1^{2}
Consider the first equation. Insert the known values of variables into the equation.
y=3+5-0.04\times 1^{2}
Multiply 3 and 1 to get 3.
y=8-0.04\times 1^{2}
Add 3 and 5 to get 8.
y=8-0.04
Calculate 1 to the power of 2 and get 1.
y=7.96
Subtract 0.04 from 8 to get 7.96.
y=7.96 x=1
The system is now solved.
