\(14+x=15\Leftrightarrow x=1;y-5=64\Leftrightarrow y=69\)

\(\Rightarrow x+y=70\)

a: \(\left(3h25p-1h40p\right)\cdot5\)

\(=\left(2h85p-1h40p\right)\cdot5\)

\(=1h45p\cdot5=5h225p=8h45p\)

b: \(\left(25p30s+1h58p50s\right):2\)

\(=\left(24p90s+118p50s\right):2\)

\(=12h45s+59p25s\)

\(=71p70s=72p10s\)

c: \(3h25p+1h40p\cdot5\)

\(=3h25p+5h200p\)

\(=8h225p\)

\(=11h45p\)

d: \(25p30s+1h58p50s:2\)

\(=25p30s+118p50s:2\)

\(=25p30s+59p25s\)

\(=84p55s\)

e: \(2h15p\cdot3+3h45p\cdot2\)

\(=6h45p+6h90p\)

\(=12h135p=14h15p\)
