Jeffrey is training to run a marathon. On Monday he ran and walked a total of 11 miles. If he ran 2 miles more than twice as far as he walked, how many miles did he run?

You just have to re arrange that equation, to make C equal to the rest of the equation.

F = 95 c + 32

F - 32 = 95c

F - 32 / (95) = c

easier if you set up a equation

r = running , w = walking

r + w =11
r = 2 + 2w 

solve for w

2 + 2w + w = 11
3w = 11 - 2
w = 9 / 3
w = 3 miles

this means he walked 3 miles

if we know how far he walked we can figure out how far he ran uysing our original equation

w + r =11
3 + r = 11
r = 11 - 3
r = 8 miles
