Answer
$(2,1)$
Work Step by Step
The y-coefficents are $+1$ and $-1$.
Add the equations ( eliminate y)
$5x=10 \quad/\div 5$
$x=2$
Back substitute into one of the equations
$ 2x+y-5$
$2(2)+y=5$
$y=5-4$
$y=1$
Solution: $(2,1)$
Graphing:
plot the x-and y-intercepts, join with line.
$\left[\begin{array}{llll}
& x=0 & y=0 & plot\\
3x-y=5 & y=-5 & x=5/3 & (0,-5),(5/3,0)\\
& & & \\
2x+y=5 & y=5 & x=5/2 & (0,5),(5/2,0)\\
& & &
\end{array}\right]$
