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
