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

Answer:
-111 and -110
Step-by-step explanation:
If x is the lesser integer, and x+1 is the next integer, then:
x + x+1 = -221
2x = -222
x = -111
x+1 = -110
The two integers are -111 and -110.
