Question

4.Verify that x=2, y=-1 is a solution of the linear equation 7x + 3y =11.​

Answer 1

Step-by-step explanation:

Given :-

1. x = 2
2. y = -1

Put the respective value of x and y

$7x + 3y = 11$

$7(2) + 3( - 1) = 11$

$14 - 3 = 11$

$11 = 11$

Since both sides are equal,

Hence verified

Answer 2

7x + 3y = 11

putting x = 2 and y = -1

LHS

7 × 2 + 3 × -1

→ 14 - 3

→ 11 = RHS

Hence verified.

Hope it help you ☺️☺️
