Question

mini lesson$y = - 3x - 10$math

Answer 1

$\begin{gathered} y=2x+5 \\ y=-3x-10 \end{gathered}$

so we have to replace y. we get

$\begin{gathered} 2x+5=-3x-10 \\ 2x+3x=-10-5 \\ 5x=-15 \\ x=-\frac{15}{5}=-3 \end{gathered}$

if x=-3, we get that y is

$y=2\cdot-3+5=-1$

so the solution is

$(-3,1)$
