Answer:
change the order, so the terms line up
20g+15m=300
g+m=17
multiply the second equation by 20, so the 20g and -20g can cancel out
20g+15m=300
-20g-20m=-340
solve the equation, then divide -5 to both sides to isolate the m
-5m=-40
m=8
substitute the value of m into one equation to find the other value
g+8=17
g=9
write them in ordered paired form
(9, 8)

Mary added 
cups of sugar.
<h3>
How to estimate how much sugar should Mary add?</h3>
The ratio of flour to sugar exists at 9 cups: 2 4/7 cups
Utilizing equivalent ratios, given that 7 cups of sugar was utilized,
Let cups of flour needed = x such that our equation becomes
flour/sugar
Convert mixed numbers into improper fractions
simplifying the above equation, we get
=
x = 24.5
The value of x = 24.5.
Therefore, cups of sugar exist required.
