Question

1
-3x + y = -2
7x - y = -2

Explanation:

Step1: Add the two equations

$$(-3x + y) + (7x - y) = -2 + (-2)$$
Simplify: $4x = -4$

Step2: Solve for $x$

$$x = \frac{-4}{4} = -1$$

Step3: Substitute $x=-1$ into first equation

$$-3(-1) + y = -2$$
Simplify: $3 + y = -2$

Step4: Solve for $y$

$$y = -2 - 3 = -5$$

Answer:

$x=-1$, $y=-5$
