Step-by-step explanation:
Answer:
x - 5 = 9
x = 14
Step-by-step explanation:
On the left side, there are 5 -1's and 1 x. On the right side, there are 9 1's. Then we set them equal and solve
Problem:
x - 5 = 9
+ 5 + 5
x = 14
The sum of three consecutive integers is three times the middle one: if we call the middle one
, the three numbers are

So, their sum is 
Which is three times the middle one.
So, if the sum of three consecutive intergers is 48, the middle one must be 48/3 = 16.
So, the three numbers are 15, 16 and 17
Answer:
x=24.5
Step-by-step explanation:
-0.5(2x-10)+15.5=45 distribute -0.5 through the parenthesis
-x+5+15.5=45 add the numbers
-x+20.5=45 move constant to the right side and change its sign
-x=45-20.5 subtract the numbers
-x=24.5 change the signs on both sides of the equation
x=-24.5
