The two original functions are 4x+9y=7 and 4x-9y=9
To use the combination method, add all the values of the two equations together to cancel out one of the variables
4x+4x+9y-9y=7+9
8x=16
8x/8=16/8
x=2
4(2)+9y=7
8+9y=7
8-8+9y=7-8
9y=-1
y=-

11:12 is the answer to your question
1. Ok so first I would find 22% of 212,000 to do that you do: 22 divide 100 = 0.22
2. Now that you’ve turned 22% into a decimal as 0.22 you find what 22% of 212,000 is like so: 0.22x212,000 =46,640
3. Now that you have to reduce 212,000 but 22% to do this you just subtract: 212,000-46,640= 165,360
They would purchase the house for $165,360
