Solution:
Given:
[tex]7a+-36=-22[/tex]Simplifying the expression further,
[tex]\begin{gathered} 7a+-36=-22 \\ +\times-=-,\text{ when a negative sign is multiplied by positive sign, the result is negative} \\ 7a-36=-22 \\ Collecting\text{ the like terms;} \\ 7a=-22+36 \\ 7a=14 \\ Dividing\text{ both sides by 7:} \\ a=\frac{14}{7} \\ a=2 \end{gathered}[/tex]Therefore, the value of a = 2
