Your answer is If Nigel walks 2 miles his mother and grandmother will each owe $8.

Your two equations are:
x=8 and 4y=x

Substitute 8 for x to get 4y=8 and solve for y
y=8/4=2

x= the amount of money
y=the number of miles

Hope that helps.

We know that his mother has pledged a flat donation of $8 while his grandmother pledged $4 per mile. Using systems we could see: 8m+4g, g=8m/4. M represents the amount of his mom's pledges and g=the amount of miles Nigel is going will run. So since m=1 we'll just use g=8/4, which we know is 2. So, Nigel will have to run 2 miles for them to both give the same amount of money.
