Question

Solve the system of equations. Enter the x-value and y-value of the solution separately, as indicated.x + 4y=39- 4x - 4y=0

Answer 1

Given:

The system of equations is

$\begin{gathered} x+4y=39 \\ -4x-4y=0 \end{gathered}$

Required:

We want to find x-values and y-values

Explanation:

First add both equations

$\begin{gathered} x+4y-4x-4y=39 \\ -3x=39 \\ x=-13 \end{gathered}$

put value of x in any of equation

$\begin{gathered} -4x-4y=0 \\ x+y=0 \\ -13+y=0 \\ y=13 \end{gathered}$

Final answer:

x-value is -13

y-value is 13
