Question

in linear equations x+y=5andx=3then find the value of y
​

Answer 1

$\bold{\underline\red{Solution}}$

x + y = 5

Put x = 3 in equation (i), we get

$$3 + y = 5$$

$$\therefore y = 5 - 3$$

$$\therefore y = 2$$

Answer 2

$\huge\mathfrak{\red{Solution:-}}$

$\sf\underline{\blue{\:\:\:\:Given:-\:\:\:\:\:}}$

$\sf \bullet x+y=5\\ \sf\:\:x=3$

We have to find the value of y

Now

$\sf\underline{\pink{A.T.Q}}$

$\sf :\implies x+y=5\\ \\ \sf :\implies 3+y=5\\ \\ \sf :\implies y=5-3\\ \\ \sf :\implies y=2$

• The value of y is 2

$\huge\underline{\purple{\mathcal{PROOF:-}}}$

• Put the value of x and y in equation

$\sf :\implies x+y=5\\ \\ \sf :\implies 3+2=5\\ \\ \sf:\implies 5=5\\ \\ \sf\:\:\:L.H.S=R.H.S$
