Question

Y=-7/4x+3;y=-1/4x-3 is my question

Answer 1

Answer:

$y = -\frac{7}{4} + 3 , y = -\frac{1}{4}x - 3 : x = 4, y = -4$

Step-by-step explanation:

$\begin{bmatrix}y=-\frac{7}{4}x+3\\ y=-\frac{1}{4}x-3\end{bmatrix}$

Substitute: $y=-\frac{1}{4}x-3$

Isolate x for: $-\frac{1}{4} x - 3 = -\frac{7}{4} x + 3 : x = 4$

For $\:}y=-\frac{1}{4}x-3$

Substitute: $x = 4$

$y=-\frac{1}{4}\cdot \:4-3$

$-\frac{1}{4}\cdot \:4-3 = - 4$

$y = -4$

The solutions to the system of equations are:

$x=4,\:y=-4$

Hope I helped, if so may I get brainliest and a thanks?

Thank you, have a good day! =)
