\(76,22-y\times3=61,22\)
\(y\times3=76,22-61,22\)
\(y\times3=15\)
\(x=15:3\)
\(x=5\)
76,22 - y * 3 = 30,61 * 2
76,22 - y * 3 = 61,21
76,22 - y = 61,22 : 3
76,22 - y = 20/61/150
y = 76,21 - 20/61/150
y = 55/241/300
\(76,22-y\times3=30,61\times2\)
\(\Leftrightarrow\)\(76,22-y\times3=61,22\)
\(\Leftrightarrow\)\(y\times3=76,22-61,22\)
\(\Leftrightarrow\)\(y\times3=15\)
\(\Leftrightarrow\)\(y=15\div3\)
\(\Leftrightarrow\)\(y=5\)
