f\times 14=4\times 14^{2}+2
Consider the second equation. Insert the known values of variables into the equation.
f\times 14=4\times 196+2
Calculate 14 to the power of 2 and get 196.
f\times 14=784+2
Multiply 4 and 196 to get 784.
f\times 14=786
Add 784 and 2 to get 786.
f=\frac{786}{14}
Divide both sides by 14.
f=\frac{393}{7}
Reduce the fraction \frac{786}{14} to lowest terms by extracting and canceling out 2.
x=14 f=\frac{393}{7}
The system is now solved.
