Question

Q-1 check if (-2,1) is a solution of the equation 2x+3y=-1 or not? please write fast and full answer with explaination​

Answer 1

Answer:

(-2,1)

x = -2, y = 1

$2x + 3y = - 1$

$2( - 2) + 3(1) = - 1$

$- 4 + 3 = - 1$

$- 1 = - 1$

As both the sides are coming same so, (-2,1) is a solution of the equation.

Ans. Yes, (-2,1) is a solution

Hope it helps.

Answer 2

$x = - 2 \: \: ,y = 1$

$2x + 3y = - 1$

$2( - 2) + 3( 1) = - 1$

$- 4 + 3 = - 1$

$- 1 = - 1$
