Answer 1

Answer:

answer for the given problem is given

Answer 2

Step-by-step explanation:

$\blue{ \bold{ \underline{QUESTION \: \: No -1}}}$

$\bold{ \sf{ \large{y = 2x ..........(1)}}}$

$\bold{ \large{ \sf{x + y = 6.........(2)}}}$

$\star{ \pink{ \large{ \sf{ \underline{ \underline{Solution : - }}}}}}$

Putting y value in Equation (2)

$\bold{ \large{ \sf{x + y = 6}}}$

$\implies{\large{ \bold{ \large{ \sf{x + 2x= 6}}}}}$

$\implies{\large{ \bold{ \large{ \sf{ 3x= 6}}}}}$

$\implies{\large{ \bold{ \large{x = \frac{6}{3}}}}}$

$\implies{\large{ \bold{ \large{x = { \cancel \frac{6}{3} = 2}}}}}$

____________________________________

$\blue{ \bold{ \underline{QUESTION \: \: No -2}}}$

$\bold{ \large{ \sf{5x + 10y = 3 .....(1)}}}$

$\bold{ \large{ \sf{x = - \frac{1}{2}y........(2)}}}$

$\star{ \pink{ \large{ \sf{ \underline{ \underline{Solution : - }}}}}}$

Puting x value in Equation (1)

$\bold{ \large{ \sf{5x + 10y = 3 }}}$

$\implies{ \bold{ \large{ \sf{5 \times (- \frac{1}{2}) y + 10y = 3}}}}$

$\implies{ \bold{ \large{ \sf{ - \frac{5}{2} y + 10y = 3}}}}$

$\implies{ \bold{ \large{ \sf{ \frac{ - 5y + 20y}{2} = 3}}}}$

$\implies{ \bold{ \large{ \sf{ \frac{15y}{2} = 3}}}}$

$\implies{ \bold{ \large{ \sf{15y = 6}}}}$

$\implies{ \bold{ \large{ \sf{y = \cancel\frac{6}{15} = \frac{2}{5} }}}}$
