If y- 18 = 14 what is the value of 3(y+5)<br>​
Len [333]
<h3>Given :</h3>

\bf y- 18 = 14

⠀ ⠀⠀ ⠀ ⠀⠀ ⠀

<h3>To Find :</h3>

\bf 3(y+5) = ?

⠀ ⠀⠀ ⠀ ⠀⠀ ⠀

<h3>Solution :</h3>

\bf It \: is \: given \: that \: y - 18 = 14

\bf \implies y = 14 + 18

\bf \implies y = 32

Now, by filling value of y in 3(y+5), we get,

\bf = 3(32 + 5)

\bf = 3 \times 37

\bf = 111

\pink{\bf Hence, \: the \: value \: of \: 3(y+5) \: is \: 111.}
