Answer:
2x+3y=170.......1
1x+5y=225.......2
multiplying equation 2 by 2 and subtracting eq.1 &2
2x+3y-2x-10x=170-225
-7x=-55
x=55/7
55/7+5y=225
5y=225-55/7
y=1520/(7×5)=304/7
The last number is in parenthesis because it's a negative: nevermind that for now.
What you want to do is 29-4.37 FIRST.
That gets you:
24.63. NOW you want to subtract the last number, because adding a negative = subtracting a positive.
24.63 - 5.68
