an antique jar is 45 years older than the mug. in 13 years, the jar will be 4 times as old as the mug will be then. find the present age of the jar
--------------
Equations:
j = m + 45
j+13 = 4(m+13)
-----
Substitute for "j" and solve for "m":
m+45 + 13 = 4m+52
3m = 58-52
m = 6/3
m = 2 years (age of the mug)
----
Solve for "j":
j = m + 45
m = 2 + 45
m = 47 years (age of the jar)
