Question 733869
Marc is 8 years younger than his brother Richard. The sum of their ages is 22 years. What equation could be used to find Marc's age? What is Marc's age?
--------
Equations:
m = r - 8
m + r = 22
----
Rearrange:
m-r = 8
M+r = 22
-------
Add and solve for "m":
2m = 30
Marc's age is 15 yrs.
------
M+r = 22
r = 7 yrs
