Pam Juan and Eva took a 1200 mile driving trip. Pam drove 110 miles more than Juan and juan drove 100 miles more than Eva How many miles did Eva drive?
btw this is supposed to be in algebra.
----
Equations:
p + j + e = 1200 miles
p = j + 110
j = e + 100
----------------------
Substitute for "p" and "e" and solve for "j"::
(j+110) + j + (j-100) = 1200
---------------------------
3j + 10 = 1200
3j = 1190
j = 396.67 miles
-----
Solve for "e"::
e = j - 100
e = 296.67 miles (distance eva drove)
