Answer

The solution of the system is $(2,7)$.

Work Step by Step

Graph both equations in the same coordinate plane. $y=5x-3$ The slope is $5$. The y-intercept is $-3$. $y=3x+1$ The slope is $3$. The y-intercept is $1$. Find the point of intersection. The lines appear to intersect at $(2,7)$. Check to see if $(2,7)$ makes both equations true. $y=5x-3 \rightarrow 7=5(2)-3 \rightarrow 7=7$ $y=3x+1 \rightarrow 7=3(2)+1 \rightarrow 7=7$ The solution of the system is $(2,7)$.
