Answer 1

$\star\:\:\:\bf\large\underline\blue{Question:-}$

• Solve the following pair of linear equation.

$\star\:\:\:\bf\large\underline\blue{Solution:-}$

Given,

$2x + 3y = 12 \: ...(i)$

$- x + 2y = 1 \: ...(ii)$

Multiplying equation (ii) by 2,we get,

$- 2x + 4y = 2 \: ...(iii)$

Adding equation (i) and (iii),we get,

$3y + 4y = 14$

$\implies 7y = 14$

$\implies y = 2$

Now,

$2x + 3y = 12$

$\implies 2x + 6 = 12$

$\implies x = 3$

$\star\:\:\:\bf\large\underline\blue{Answer:-}$

• $x = 3 \: and \: y = 2$
