Answer:
x = -1
y = 1
Step-by-step explanation:
y = x + 2
y = 3x + 4
since both of these equal y, you can rewrite this as one equation:
x + 2 = 3x + 4
subtract x from both sides of the equation
2 = 3x + 4 - x
2 = 2x + 4
subtract 4 from both sides of the equation
2 - 4 = 2x
-2 = 2x
divide both sides of the equation by 2
-2/2 = x
-1 = x
now you can plug this back into the original equation to find y.
y = x + 2
y = -1 + 2
y = 1
