Question

Solve in systems by substitution y=x+2 and 3x+3y=6

Answer 1

x = 0, y = 2

Explanation:

y = x + 2

3x + 3y = 6

3x + 3(x + 2) =6

3x + 3x +6 = 6

6x = 0

x = 0

y = x + 2 = 0 + 2 = 2

Answer 2

x = 0, y = 2

Explanation:

Substitute the first equation into the second equation so 3x + 3(x+2) = 6. Simplify this to get x = 0. Plug x = 0 back into the first equation to get y = 2.
