Decide if the system of equations in two variables is linear or nonlinear.
-$$\left\{ \begin{array} { l } 
x ^ { 3 } + 3 x = y \
x + 7 y = 3
\end{array} \right.$$
A) Linear
B) Nonlinear

Quizplus · Accepted Answer

The system is nonlinear because the first equation contains a cubic term ($x^3$), which does not fit the definition of a linear equation (which would only have variables to the first power).
