Question

-5x-3y=11,-10x+6y=-22​

Answer 1

Solution:-

We have

$\rm \to \: - 5x - 3y = 11 \: \: \: \: \: \: \: \: .....(i)eq$

$\rm \to - 10x + 6y = - 22 \: \: \: \: \: \: \: ...(ii)eq$

Now take ii eq

$\rm \to - 10x + 6y = - 22 \: \: \: \: \: \: \: ...(ii)eq$

Take a 2 common from equation

$\rm \to \: 2( - 5x + 3y) = - 22$

$\rm \to \: - 5x + 3y = - 11 \: \: \: \: \: \: \: ...(iii)eq$

Now add (i) eq and (iii) eq

$\rm \to \: - 5x + 3y - 5x - 3y = - 11 + 11$

$\rm \to - 10x = 0$

$\rm \to \: x = 0$

Now put the value of x (iii) eq

$\rm \to \: - 5x + 3y = - 11 \: \: \: \: \: \: \:$

$\rm \to \: 5 \times 0 + 3y = - 11$

$\rm \to \: 3y = - 11$

$\rm \to \: y = \dfrac{ - 11}{3}$
