Question

Solne and check- y by 4 + 1 by 2= 5​

Answer 1

Given:

$\sf{\leadsto \frac{y}{4}+\frac{1}{2}=5}$

To Find:

$\sf{\leadsto The \:value\:of\:y}$

Answer:

$\sf{\implies \dfrac{y}{4}+\dfrac{1}{2}=5}$

$\sf{\implies \dfrac{y+2}{4}=5}$

$\sf{\implies (y+2)=5\times 4}$

$\sf{\implies y+2=20}$

$\sf{\implies y =(20-2)}$

${\underline{\boxed{\red{\longmapsto \bf{y=18}}}}}$

$\rule{200}1$

${\underline{\underline{\bf{\orange{\hookrightarrow Check:}}}}}$

$\green{\sf{LHS}}$

=$\sf{\dfrac{y}{4}+\dfrac{1}{2}}$

$\sf{\pink{\leadsto Putting\:y\:=\:18}}$

=$\sf{\dfrac{18}{4}+\dfrac{1}{2}}$

=$\sf{\dfrac{18+2}{4}}$

=$\sf{\dfrac{20}{4}}$

=$\sf{\dfrac{\cancel{20}^{5}}{\cancel{4}}}$

=${\underline{\bf{\blue{5}}}}$

=$\green{\sf{RHS}}$

${\underline{\boxed{\purple{\bf{Hence\:Checked}}}}}$
