We have two equations and two unknowns/variables
y = 2x + 4
y = x + 2
We can solve by substitution or by elimination.
Let's try substitution.
Since both equations are set equal to y, set the two equations equal to one another and solve for x.
x + 2 = 2x + 4
Use algebra to solve
x = -2
Now use this value of x in one of the original equations to solve for y.
y = x + 2
y = -2 + 2
y = 0
So the solution is (-2,0).
