a)2x+8y=17 b) solve x^2+y^2=4
3x-5y=4 x+y=1

Solution Preview

Hi!

Part A:
2x+8y=17
3x-5y=4

Multiply the first equation by 3:
6x + 24y = 51

Multiply the second equation by -2:
-6x + 10y = -8

Add those two new equations:
34y = 43

Divide by 34:
y = 43/34

Solve for x with the first equation:
2x + 8*43/34 = 17

Subtract 8*43/34:
2x = 17 - ...
