Question 143506
see this --> http://collabvsl.wetpaint.com/page/Solving+Systems+of+Equations


4x - 2y = 8
2x + 4y =8

2x + 4y = 8
2x = 8 -4y
x = (8-4y)/2    use this and sub into the first equation

4x - 2y = 8
4((8-4y)/2) - 2y = 8
16 - 8y - 2y = 8
-10y = -8
y = 4/5

Use this value of y to sub back in and solve for x

x = 12/5
