Hi Jessica A

(1/5, 6) is where your lines below intersect

Given

You can make a direct substitution for y and solve in terms of x as follows:

5x + 20x + 2 = 7

Combine like terms

25x + 2 = 7

Subtract 2 from both sides of the equation

25x = 5

Divide both sides by 25

x = 1/5

Substitute this value for x in the second equation to solve for y

20x + 2 = y

20(1/5) + 2 = y

4 + 2 = y

6 = y

Check by using this values for x and y in the original equations given

5x + y = 7

5(1/5) + 6 = 7

1 + 6 = 7

7 = 7

And we already know

20x + 2 = y

20(1/5) + 2 = y

4 + 2 = y

6 = y
