Answer:
x = -3
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 6 from both sides:
6x + 6 (-6) = -12 (-6)
6x = -12 - 6
6x = -18
Isolate the variable, x. Divide 6 from both sides:
(6x)/6 = (-18)/6
x = (-18)/6
x = -3
x = -3 is your answer.

Answer:
Step-by-step explanation:
Let's look at the first two, and hopefully you'll be able to figure the rest out:
1. Answer below

The problem asks us to solve for
, so that means we need to get
on one side of the equation by itself. To do so, we will need to divide both sides of the equation by
:


2. Answer below

The problem asks us to solve for
, so that means we need to get
on one side of the equation by itself. To do so, we will need to add
to both sides of equation:


Answer:
