Question

6) Mandy and 2 friends bought some mechanical pencils at a special sale. They divided some of the pencils
equally among themselves and then gave 3 to Mandy's little brother. At that time they had 19 pencils left.
- 3 - 19 to find the number of pencils p that they bought at the sale.
2. 48 pencils b. 37 pencils € 66 pencils
d. 22 pencils
Solve the equation-

Answer 1

\[\frac{ p }{ 3 }-2=17\]
So let's try to get this to equal:
\[\frac{ p }{ 3 }=19\]
Do you know what to do first?

Answer 2

Oh the user went offline, here's the work:
\[\frac{ p }{ 3 }-2=17\]
\[~~~~~+2~~~+2\]
Add two to both sides
\[\frac{ p }{ 3 }=19\]
Put the 19 over 1.
\[\frac{ p }{ 3 }=\frac{ 19 }{1 }\]
Cross mutiply:
\[3\times19=57\]
\[1\times p=1p\]
\[\frac{ 57 }{ 1p }\]
then p=57.
