Answer 1

Answer:

Step-by-step explanation:

$\large\tt \qquad \qquad x+y=7$

$\large\tt \qquad \qquad y=7-x$

$\large\tt \qquad \qquad xy=2$

$\large\tt \qquad \qquad x(7-x)=2$

$\large\tt \qquad \qquad 7x-x^2=2$

$\large\tt \qquad \qquad x^2-7x+2=0$

$\large\sf \qquad \qquad by\: using\: quadratic \:formula$

$\large\tt \qquad \qquad x≈6.7$

$\large\tt \qquad \qquad put \: value\: of\: x$

$\large\tt \qquad \qquad x+y=7$

$\large\tt \qquad \qquad 6.7+y=7$

$\large\tt \qquad \qquad y=7-6.7$

$\large\tt \qquad \qquad y=0.3$
