In this question, you're solving the systems of equations to find what x and y equal to.
Solve the systems of equations:
x + y = 3
x + 2y = 6
Lets make the "y" variable the same by multiplying the top equation by -2.
-2(x + y = 3)
x + 2y = 6
----------------
-2x -2y = -6
x + 2y = 6
Solve:
-x =0
x = 0
Now, we know x = 0, now plug 0 into x in one of the equations and solve:
We'll plug it into the x + y = 3 equation.
0 + y = 3
y = 3
When you're done solving, you should get:
x = 0 and y = 3
Answer:
x = 0
y = 3
