Question

Find the value of k , if x = 3 ,y = ( -2 ) is a solution of the equation of 3x + 2y = k​

Answer 1

Answer:

5

Step-by-step explanation:

3x + 2y = k

(3×3) + (2× -2) = k

9 + (-4) = k

9 - 4 = k

k = 9 - 4

∴ k = 5

Answer 2

Given:-

• x = 3
• y = (-2)

⠀

Given Equation:-

• 3x + 2y = k

⠀

To find:-

• Value of k.

⠀

Solution:-

If,

• x = 3
• y = (-2)

⠀

Then,

$\large{\tt{\longmapsto{3x + 2y = k}}}$

⠀

$\large{\tt{\longmapsto{3 \times 3 + 2 \times (-2) = k}}}$

⠀

$\large{\tt{\longmapsto{9 + (-4) = k}}}$

⠀

$\large{\tt{\longmapsto{9 - 4 = k}}}$

⠀

$\boxed{\large{\tt{\longmapsto{\red{k = 5}}}}}$

⠀

Hence, the value of k is 5.
