Answer:X=4Step-by-step explanation: You need to distribute the 5 to the value in the parentheses.A. 5X- 30 +3= -7The next thing that you are going to want to do is simplifyB. 5X-27=-7After 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= 20Now 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=20/5You should be left with x= 20/5. Simplify.E. X= 4
