Go backwards:
"regainged 5 pounds and weighed 179 pounds."
so he weiged 1795=174 pounds.
"and lost 26 pounds" to weigh 174 pounds,
so he used to weigh 174+26=200 pounds
"david gained 14 pounds over the winter." so he weighed 20014=186 pounds.
Check 186+1426+5=179 pounds
If you are doing algebra, then
X+1426+5=179
Solve for X.
