Question

x + y =3 and x-y=0 in substitution method​

Answer 1

Answer:

$x = \frac{3}{2}$

and,

$y = \frac{3}{2}$

Step-by-step explanation:

$x + y = 3$

so,

$x = 3 - y$

now , put the value of x in 2nd equation,

$3 - y - y = 0$

so,

$3 - 2y = 0$

$y = \frac{3}{2}$

and,

$x = 3 - \frac{3}{2}$

so,

$x = \frac{3}{2}$
