Question

Solve the system of linear equations by substitution. 3x + y = -3 -2x + y =7

Answer 1

Answer:

(-2, 3)

Step-by-step explanation:

First solve one equation for y:

$-2x+y=7\\y=7+2x$

Now we can substitute this equation into the other one:

$3x+7+2x=-3$

Solve for x:

$x=-2$

Now substitute this value into the equation $y=7+2x$:

$y=7+2x(-2)$

Solve for y:

$7=3$

Now your solution is (-2,3)

Hope this helps! :)

Answer 2

Both equations are equal to 0
