Answer:
The two numbers are .8*160=128 and .85*240=204
Step-by-step explanation:
First sentence: x+y=400
Second sentence .8x+.85y=400-68
Solve y in the first sentence: y=400-x
Plug first into second: .8x+.85(400-x)=332
Distribute: .8x+.85(400)-.85x=332
Combine like terms: -.05x+.85(400)=332
Simplify(multiply): -.05x+ 340=332
Subtract 340 on both sides: -.05x =332-340
Simplify(subtract): -.05x =-8
Divide both sides by -.05: x =-8/-.05
Simplify (division): x = 160
So y=400-x=400-160=240
This transformation is called a rotation:-D
X-number
8x-20=15+x (subtract x)
7x-20=15 (then add 20)
7x=35 (then divide by 7)
I think you've got it from now, if not, just do 35 divided by 7. But go over the steps, so that you know how to do these types of questions.
