What do we need to do to this system to get it ready for elimination?
Multiply the top equation by 25.
multiply the bottom equation by 25.
Multiply the top equation by 2.
Multiply the bottom equation by 2.
3
What do I need to do now?
Write your final answer.
Solve for x.

Add the two equations.
Substitute in for x.
5
How do I solve for x?
Subtract the equations again.
Substitute x into one of the original equations
Divide everything by the 2 on the x.

6
How would I solve for y after I subtract?
Divide both sides of the equation by -1.
Divide y by -1.
Divide both sides of the equation by 2.

7
How do we write our final answer?
We already did!
We don't we just skip that part.
As two numbers.
As a coordinate point.
8
Solve the equation for x.
x = 25
y = 0
x = -25
x = 0
