Answer:

See below

Step-by-step explanation:

y = 2x + 4 Substitute this for y in the second equation

6x - 3y = -12

6x - 3(2x + 4) = - 12 Substitute this for y for 2x + 4

6x - 3(2x) -3(4) = - 12 Distributive property

6x - 6x - 12 = - 12

(6x - 6x) -12 = - 12 like terms together

0 - 12 = - 12 Simplify

-12 = -12 True equation so x is equal to any number and you have the same equation

I know this right away because notice how it says “EACH month.” When it includes each you have to have an “x” beside the number to make it each month. If you don’t have an x it will just be “a single month.”

Sorry if that’s confusing I’m bad at explaining but have a nice day:))
