Answer:

$\large\boxed{x=-2}$

Step-by-step explanation:

How to solve equations?

To solve equations we use four mathematical operations: Addition, Subtraction, Multiplication and Division. Most of the time, two or more of these operations will be needed.

The first operation to be used in this equation is Multiplication. What's going to be multiplied is $-5$ by $6x+6$:

$-5(6x+6)=30$

$-30x-30=30$

→ Add $30$ to both sides.

$-30x=60$

→ Divide $-30$ into both sides.

$-30x=60$

$-x=2$

→ Multiply both sides by $-1$.

$x=-2$
