Question

8. Which of the following is a solution of the equation:
-5x+2y = 14
a) x = 0, y = -7
b)x= -2, y = 2
c) x = 1, y = -3
d) x = 5, y = 1​

Answer 1

Answer:

b) x= -2, y=2

Step-by-step explanation:

Let's put vaules in the equation..

-5 ×-2+2×2 = 14

10 + 4 = 14

14=14

Hence, Verified.....

Answer 2

Answer:b) x= -2, y= 2

Step-by-step explanation:

Given equation- -5x+2y=14

b) Putting value of x=-2 and y=2

We get,

LHS

-5(-2)+2(2)

=10+4

=14

RHS

=14

here, LHS=RHS

hence verified

You can use the similar method for other options to show that they do not verify the equation
