Question

Determine whether the given ordered pair is a solution of the system.
-$$\begin{array} { l } 
( 1 , - 6 ) \
3 x + y = 9 \
4 x + 3 y = 22
\end{array}$$
A) not a solution
B) solution

Quizplus · Accepted Answer

Substituting $x=1$ and $y=-6$ into the equations, we have:
\begin{align*}
3x+y &= 3(1)+(-6) = -3 
eq 9 \
4x+3y &= 4(1)+3(-6) = -14 
eq 22
\end{align*}
Therefore, $(1,-6)$ is not a solution of the system.
