• Solve the following pair of simultaneous linear equation.

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

Given equations,

$2x + y = 11 \: ....(i)$

$x + y = 8 \: ....(ii)$

It is easy to solve the equation by elimination method. So, we will solve by using this method only.

Subtracting equation (ii) from equation (i),we get,

$2x + y - x - y = 11 - 8$

$\implies x = 3$

Now, substituting the value of x in the equation (ii), we get,

$3 + y = 8$

$\implies y = 5$

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

• The value of x and y are 3 and 5 respectively.
