Answer:
a)
[tex]{ \tt{2x = 169}}[/tex]
• divide all sides by 2 following division property of equality:
[tex]{ \tt{ \frac{2x}{2} = \frac{169}{2} }} \\ \\ { \tt{ \underline{ \: \: x = 84 \frac{1}{2} \: \: }}}[/tex]
b)
[tex]{ \tt{3x = - 125}}[/tex]
• divide all sides by 3 following division rule of equality:
[tex]{ \tt{ \frac{3x}{3} = \frac{ - 125}{3} }} \\ \\ { \tt{ \underline{ \: \: x= -41.67 \: }}}[/tex]
