Answer:

3x = -9

Step-by-step explanation:

Move all terms containing x to the left side of the equation.

2x-4=-10

Move all terms not containing  x to the right side of the equation.

2x=-6

Divide each term by  2 and simplify.

x=-3

Replace the variable x with -3 in the expression.

3(-3)

Multiply 3 by -3

-9
