Question

What is the solution to the system of equations? Use the substitution method to solve the system of equations. Show all of your work! Y = x + 5 4x ? 4y = ?20

Answer 1

The solution would be (0, 5)

Explanation:

In order to solve this system by substitution, simply take the value of y in the first equation and use it in place of y in the second. This will allow you to solve for x.

4x + 4y = 20

4x + 4(x + 5) = 20

4x + 4x + 20 = 20

8x + 20 = 20

8x = 0

x = 0

Now that we have the value of x, we can find the value of y.

y = x + 5

y = 0 + 5

y = 5
