X=205
y=41
You come across these answers by making an equation or system of equations based on the word problem given. 1. x+y=246 and 2. x÷y=5 . The you would multiply by y on both sides and get x=5y . Then you would substitute for x in the first equation and get (5y)+y=246 . Then you would get 6y=246 . Them you would divide by 6 on both sides and get y=246÷6 . Then you would get y=41. Then you would plug the y value into the first equation. You would get that x+(41)= 246, subtract on both sides and get x=246-41, then you would get an answer of x=205.
