Answer:

X=4

Step-by-step explanation:

You need to distribute the 5 to the value in the parentheses.

A.       5X- 30 +3= -7

The next thing that you are going to want to do is simplify

B.       5X-27=-7

After you simplify or combine like terms you will need to add (-27) from both sides of the equation to aide in getting the variable alone. (You do the opposite of whatever you see ex: subtraction means you add, multiplication implies you divide... etc.) You add first because when going through one and two step equations Pemdas becomes backwards.

C.       5X= 20

Now what you are going to do is divide both sides by 5 because you need to get the variable alone on one side of the equation.

D.       5X/5=20/5

You should be left with x= 20/5. Simplify.

E.       X= 4
