  1. The value of [tex]x[/tex] is [tex] \frac{ – 1}{5} [/tex]

    [tex]9x + 6 = 5 + 4x \\ ➡ \: 9x – 4x = 5 – 6 \\ ➡ \: 5x = – 1 \\ ➡ \: x = \frac{ – 1}{5} [/tex]

    To check:

    [tex]9x + 6 = 5 + 4x \\ ➡ \: 9 (\frac{ – 1}{5} ) + 6 = 5 + 4( \frac{ – 1}{5} ) \\ ➡ \: \frac{ – 9}{5} + 6 = 5 – \frac{4}{5} \\ ➡ \: \frac{ – 9}{5} + \frac{6 \times 5}{1 \times 5} = \frac{5 \times 5}{1 \times 5} – \frac{4}{5} \\ ➡ \: \frac{ – 9 + 30}{5} = \frac{25 – 4}{5}\\➡\: \frac{21}{5}=\frac{21}{5} [/tex]

    Hence checked.
