Can someone me with algebraic method

x = -8; y = 0

Step-by-step explanation:

x + 2y = -8

3x - 4y = -24

We will use the substitution method.

Solve the first equation for x.

x = -8 - 2y

Replace x of the second equation with -8 - 2y, and solve for y.

3x - 4y = -24

3(-8 - 2y) - 4y = -24

-24 - 6y - 4y = -24

-24 - 10y = -24

-10y = 0

y = 0

Now we substitute 0 for y in the first original equation and solve for x.

x + 2y = -8

x + 2(0) = -8

x + 0 = -8

x = -8

Solution: x = -8; y = 0
