[tex] = 5( + \frac{2}{5} ) = - 18[/tex]
[tex] = 5y + \frac{10}{5} = - 18[/tex]
[tex] = 5y + 10 = - 18 \times 5[/tex]
[tex] = 5y + 10= - 90[/tex]
[tex] = 5y = - 90 - 10[/tex]
[tex] = 5y = - 100[/tex]
[tex] = y = \frac{ - 100}{5} [/tex]
[tex] = y = - 20[/tex]
[tex]Therefore, the \: value \: of \color{hotpink} \ y \: = - 20[/tex]
