Systems of Linear Equations in Three Variables
1 Verify the Solution of a System of Linear Equations in Three Variables
-$$\begin{aligned}
( 5,2 , - 2 ) \
x + 3 y + 4 z & = 24 \
5 y + 5 z & = 35 \
z & = 5
\end{aligned}$$
A) not a solution
B) solution

Question

Quizplus · Accepted Answer

To verify the solution, substitute $x = 5$, $y = 2$, and $z = -2$ into each equation. The third equation $z = 5$ is not satisfied since $z = -2$. Therefore, (5, 2, -2) is not a solution.
