when x = 3 ; y = 2

\bold\blue{✯\:\:\:2x + y}

substitue x = 3 and y = 2 in the given equation !

\bold{2(3) + 2 = 6 + 2 } \\  \bold{ =  > 8}

<h2>—————————————</h2>

<h2>2 ) </h2>

We've to divide 328 in the ratio of 1 : 3

let the respective distribution be x and 3x.

Then ,

\bold{x + 3x = 328} \\\bold{ 4x = 328 }\\ \bold{x =  \cancel\frac{328}{4} } \\  \\ \bold{x = 82}

the respective shares are :

x = $82

3x = $246

<h2>3 ) </h2>

6 pens cost $90

therefore ,

cost of 1 pen =

\cancel \frac{90}{6}  = 15 \\

further ,

cost of 9 such pens = $15 × 9 = $135
