\[8 + x = 28\]

\[60 - x = 30\]

\[y - 14 = 24\]

\[Решим.\]

\[8 + x = 28\]

\[x = 28 - 8\]

\[x = 20.\]

\[18 + x = 28\]

\[x = 28 - 18\]

\[x = 10.\]

\[50 - x = 30\]

\[x = 50 - 30\]

\[x = 20.\]

\[60 - x = 30\]

\[x = 60 - 30\]

\[x = 30.\]

\[y - 14 = 24\]

\[y = 24 + 14\]

\[y = 38.\]

\[y - 4 = 24\]

\[y = 24 + 4\]

\[y = 28.\]
