Answer 4

The x is being `multiplied` by 7.
In order to isolate the x, we'll perform the inverse of multiplication.
So divide both sides by 7.
\[\large\rm \frac{7x}{7}=\frac{-54}{7}\]The division and multiplication on the left "cancel out",\[\large\rm x=\frac{-54}{7}\]

Answer 5

And from there, simplify, ya?
