Hi

Let x represent the number

Write as we Read***

 (x/12)*7 - 5 + 13 = 15

Solving for x

 7x - 60 + 13*12 = 15*12 Multiplying @ term by 12 so as all denominaors = 1

 7x - 60 + 156 = 180 

        7x = 84

         x = 12

CHECKING our Answer***

  7 - 5 + 13 = 15

 Let x=the whole #

Divide it by 12: x/12

Multiply ans by 7: 7(x/12)=7x/12

Then subtract 5: (7x/12)-5

And then add 13:  ((7x/12)-5)+13

And the above equals 15: Sooooo

((7x/12)-5)+13=15  get rid of parens

7x/12-5+13=15 simplify

7x/12 +8=15 subtract 8 from each side

7x/12=7  multiply each side by 12

7x=84

x=12----the whole #



CK

divide by 12=12/12=1

Multiply by 7=7*1=7

Subtract 5=7-5=2

Add 13=13+2=15

15=15



Hope this helps-ptaylor
