\[\textbf{а)}\ x\ :9,6 = 17,38\ \]

\[x = 17,38 \cdot 9,6\]

\[x = 166,848.\ \]

\[\textbf{б)}\ y\ :0,052 = 3,451\ \]

\[y = 3,451 \cdot 0,052\]

\[y = 0,179452.\]

\[\textbf{в)}\ a - 0,961 = 9,51\]

\[a = 9,51 + 0,961\]

\[a = 10,471.\]

\[\textbf{г)}\ b + 13,001 = 17\]

\[b = 17 - 13,001\]

\[b = 3,999.\]

\[\textbf{д)}\ 10 - x = 8,341\ \]

\[x = 10 - 8,341\]

\[x = 1,659.\]

\[\textbf{е)}\ 17,345 + y = 20,991\ \]

\[y = 20,991 - 17,345\]

\[y = 3,646.\]

\[\textbf{ж)}\ x\ :0,5 = 9,756\]

\[x = 9,756 \cdot 0,5\]

\[x = 4,878.\]

\[\textbf{з)}\ y\ :2,43 = 45,9\]

\[y = 45,9 \cdot 2,43\]

\[y = 111,537.\]
