Question

27.) When 7 is added to 3 times a certain number, the result is 22”

Answer 1

The number is 5/2 or 2.5

7 is added to six times a number, the result is 22

The number sentence is interpreted this way:

7+6n=22

6n=22–7

6n=15

The goal here is to find out the value of n.

Let’s divide both sides of the equation with 6

6n/6=15/6

n= 5/2 or 2.5

Let’s check by substituting the value of n to the given equation.

Always remember to follow the PEMDAS rule. We will deal with Multiplication and Addition after.

If n=2.5

7+6n=22

7+6(2.5)=22

7+15=22

22=22

Given the result, this means that the value of the number represented by n is 2.5 or 5/2.

Answer 2

Answer:

3x+7=22   <- That's the equation

3x -7=22-7

  3x =15

3/3  =15/3

  x =5
