Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{e = - 4}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{6(3 - e) = 42}[/tex]

Distribute 6 through the parentheses

⇒[tex] \sf{18 - 6e = 42}[/tex]

Move 18 to right hand side and change it's sign

⇒[tex] \sf{ - 6e = 42 - 18}[/tex]

Subtract 18 from 42

⇒[tex] \sf{ - 6e = 24}[/tex]

Divide both sides of the equation by -6

⇒[tex] \sf{ \frac{ - 6e}{ - 6} = \frac{24}{ - 6} }[/tex]

Calculate

⇒[tex] \sf{e = - 4}[/tex]

Hope I helped!
