Question

Find the solution to the system of equations.

Answer 1

Answer:

$(-2,-5)$

Step-by-step explanation:

$\begin{bmatrix}y=-4x-3\\ y=-2x+1\end{bmatrix}$

$\mathrm{Substitute\:}y=-2x+1$

$\begin{bmatrix}-2x+1=-4x-3\end{bmatrix}$

Isolate x for -2+1=-4x-3: x=-2

$\mathrm{For\:}y=-2x+1$

$\mathrm{Substitute\:}x=-2$

$y=-2\left(-2\right)+1$

$-2(-2)+1=5$$4+1=5$

$y=5$
