Because both equations are to find Y, set them equal to each other to solve:
3x+6 = x+2
Subtract x from both sides:
2x + 6 = 2
Subtract 6 from both sides:
2x = -4
Divide both sides by 2:
x = -4 /2
x = -2
Now you have a value for x, replace X with -2 in one of the equations and solve for y:
y = 3x +6 = 3(-2) +6 = -6 +6 = 0
X = -2 and Y = 0
(-2,0)
