1.) x - 2y = 4 , add 2y to both sides. ---> answer is, X = 2y + 4
2.) 2x - 6y = 8, Add 6y to both sides, then divide both sides by 2. --> answer is, X = 3y + 4

Hi there!

To solve this system with substitution, we need to set x equal to [its value] and plug it into the second equation.

x = 2y + 4

2(2y + 4) - 6y = 8
4y + 8 - 6y = 8
-2y + 8 = 8
-2y = 0
y = 0

Now, we plug y into the equation and solve for x.

x = 4

Hope this helps!
