Question

if x=-2 and y=3 is a solution of the equation 3x-5y=a, then value of a is?

Answer 1

Step-by-step explanation:

3×(-2) _ 5×3= a

-6-15=a

a=-21

Answer 2

EXPLANATION :-

GIVEN :-

• x = -2, y = 3 is a solution of the equation 3x - 5y = a.

TO FIND :-

• Value of k.

SOLUTION :-

⟹ 3x - 5y = a

⟹ 3(-2) - 5(3) = a

⟹ -6 - 15 = a

⟹ -21 = a

VERIFICATION :-

⟹ 3x - 5y = a

⟹ 3(-2) - 5(3) = -21

⟹ -6 - 15 = -21

⟹ -21 = -21
