\begin{gathered}\begin{array} { l } { y = 10 \times x \ldots . ( 1 ) } \\\\ { y = x + 54 \ldots . ( 2 ) } \end{array}\end{gathered}

\begin{gathered}\begin{array} { l } { 10 \mathrm { x } = \mathrm { x } + 54 } \\\\ { 10 \mathrm { x } - \mathrm { x } = 54 } \\\\ { 9 \mathrm { x } = 54 } \\\\ { \mathrm { x } = \frac { 54 } { 9 } = 6 } \end{array}\end{gathered}
