Question

it's a math problem tht my little sis needs help with understanding

Answer 1

Dear Faith,

     The best thing to start with is to highlight or underline all important information.

                       

                   9*X                               +         4  =58                  Find X 

 

The product of a number and 9, increased by 4, is 58.  What is the number?

 

1.  Write down everything that you know.    Let "X=unknown amount."       is means =         product  means  times *

 

increased    +

 

2.  Set up the equation:    9X + 4 = 58    To solve for "X," you need to get numbers on one side and X's on the other

 

side of the equal sign.

3.  To solve for "X," you need to get rid of 4.  Therefore, you subtract it from both sides of the equation.

 

9X+4-4= 58-4                  

 

9X=54                 The problem is saying that 9 times X is 54.  To solve for "X,"  we need to divide both sides of

 

the equation by the number (9) next to "X."

 

9/9 (X) = 54/9                      1X=  6        Answer

 

4.  Check the problem by substituting your answer back inside the equation:

 

9(6) + 4 = 58                54 +4= 58    58=58   Check     The answer is correct because the equation is true.
