Answer 1

Answer:

Step-by-step explanation:

Answer 2

$\large{\underbrace{\sf{\red{Required\:answer:}}}}$

$\sf\pink{Given \:Equation}$ $\sf{= 4y- \large\frac{3} {7}}$$\sf{=3}$

$\sf\pink{To\: find :}$ $\sf{The \:value\: of \:7y-5\: = \:?}$

$\sf\pink{Solution:}$

$\sf{4y- \large\frac{3} {7}}$$\sf{=3}$

$\sf{⇒4y=3+ \large\frac{3} {7}}$

$\sf{⇒4y= \large\frac{21+3} {7}}$

$\sf{⇒y= \large\frac{21+3} {4×7}}$

$\sf{⇒y= \large \cancel\frac{24} {28} = \frac{6} {7}}$

$\sf{Now,}$

$\sf{⇒7y-5 }$

$\sf{\large⇒\cancel \frac{7}{1}}$$\sf \large{ \times \: \cancel\frac{6} {7}}$$\sf{-5}$

$\sf{⇒6-5}$

$\sf{⇒1}$
