Answer 2

☑️ Given Equations :

• x + y = 15 ---(1)
• x - y = 7 ---(2)

━━━━━━━━━━━━━━━━━━━━━━━━

☑️ To Find :

• value of x
• value of y

━━━━━━━━━━━━━━━━━━━━━━━━

$\huge{\{\blue{\boxed{\boxed{\mathfrak{\underline{\underline{\green{\bigstar{.SoLuTiOn.}}}}}}}}}$

━━━━━━━━━━━━━━━━━━━━━━━━

On adding both the sides of the equations ---(1) and ---(2),

$\implies$ x + y + x - y = 15 + 7

$\implies$ 2x = 22

$\implies$ $x = \frac{22}{2}$

$\implies$ $\large{\boxed{\sf{\underline{\pink{x = 11 }}}}}$

Now,

putting the value of x in any of the equation (here i'm taking equation ---(1),

$\implies$ x + y = 15

$\implies$ 11 + y = 15

$\implies$ y = 15 - 11

$\implies$$\large{\boxed{\sf{\underline{\pink{ y = 4}}}}}$
