Question

if x+2y=3 and 2x+y=6 then find x+y​

Answer 1

⭐Solution⭐

✏given here

x + 2y = 3.....(1)

2x + y = 6....(2)

multiply by 2 in (1) and subtract its

2x +4y = 6.....(3)

2x +y =6........(4)

Subtract its ,

=> 3y = 0

=>y = 0

by (1),

x +3×0 = 3

=> x = 3

✏Thus:-

Value of x = 3

Value of Y = 0

So,

X+y = 3+0

= 3

✔Hopes its helps u.

Answer 2

$\huge\mathcal{\underline{\underline{.... Answer....}}}$

$\large\bold{\mathcal{Given:}}$

1)X + 2y = 3

X = 3 - 2y

2)2x + y = 6

REPLACE THE VALUE OF X IN THE ABOVE EQUATION

2(3 - 2y) + y = 6

6 - 4y + y = 6

6 - 3y = 6

- 3y = 6 - 6

y = $\frac{0}{-3}$

y = 0

REPLACE THE VALUE OF Y IN THE ABOVE EQUATION

X + 2(0) =3

X + 0 = 3

X = 3 - 0

X =3

$\large\bold{\boxed{\boxed{x\:=\: 3\: and \:y \:=\: 0}}}$
