Question 1037995
A man is 26 years older than his son. 
<pre><b>
M = S+26
</pre></b>
He is also 8 years older than three times his son's age. 
<pre><b>
M = 3S+8

{{{system( M=S+26,M=3S+8)}}}

Substitute S+26 for M in the second equation and solve for S.
Then substitute what you get in one of those to find M.
