Answer: (5,1)

Explanation:

Substitution is where you "plug in" an equation equal to a variable to another equation that contains that variable.

Here you would subtract x from the second equation, leaving you with

-5y = -x.

You can multiply both sides by -1 to get 5y = x

Then, because 5y is equal to x, you plug in 5y where it says x on the first equation.

Now you have 4(5y) + 3y = 23. That simplifies to 20y + 3y = 23, and then 23y = 23

Divide and you get "y = 1"

Now you that you know what y is equal to, you plug in the value for y to either equation and solve for x to find the (x,y) coordinates.

4x + 3(1) = 23

4x + 3 = 23

4x = 20

x = 5

Final answer is (5,1)
