Answer:
[tex] \boxed{ \bold { \huge{ \boxed{ \sf{x = - 5}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{ - 9 = 3x + 6}[/tex]
Swap the sides of the equation
[tex] \longrightarrow{ \sf{3x + 6 = - 9}}[/tex]
Move 6 to right hand side and change its sign
[tex] \longrightarrow{ \sf{3x = - 9 - 6}}[/tex]
The negative integers are always added but possess the negative ( - ) sign
[tex] \longrightarrow{ \sf{3x = - 15}}[/tex]
Divide both sides by 3
[tex] \longrightarrow{ \sf{ \frac{3x}{3} = \frac{ - 15}{3} }}[/tex]
Calculate
[tex] \longrightarrow{ \sf{x = - 5}}[/tex]
Hope I helped!
Best regards! :D
