Question

If (3,2) is a solution of 2x+3y=k, then value of k is * a)13 b)12 c)15 d)-13​

Answer 1

$\huge\boxed{\fcolorbox{red}{blue}{Answer}}$

2x+3y = k

x= 3 , y = 2 (given)

Placing value we get equation as -

2(3) + 3 (2) = k

6 + 6 = k

12 = k

Thus 12 is the answer

Answer 2

• Let x = 3 and y = 2, Then,
• 2x + 3y = k
• After substituting the values, 2×3 + 3×2 = k
• 6 + 6 = k
• 12 = k
• Ans :- option - (b) 12
