Answer :

[tex]\begin{gathered} y=2x+5 \\ y=-3x-10 \end{gathered}[/tex]

so we have to replace y. we get

[tex]\begin{gathered} 2x+5=-3x-10 \\ 2x+3x=-10-5 \\ 5x=-15 \\ x=-\frac{15}{5}=-3 \end{gathered}[/tex]

if x=-3, we get that y is

[tex]y=2\cdot-3+5=-1[/tex]

so the solution is

[tex](-3,1)[/tex]
