Question

If (3,-2 ) is the solution of the equation 3x -2y = k then find the value of k.

Answer 1

Answer:

10

Step-by-step explanation:

3x-2y=k

put the given value that (x, y)=(3,-2)in the equation

i. e 3(2)-2(-2)=k

6-(-4)=k

10=k

Answer 2

$\dag\:\underline{\sf AnsWer :}$

• We are given that,(3,-2 ) is the solution of the equation 3x - 2y = k.
• We need to find the value of k.

$:\implies\sf 3x - 2y = k \quad ... \bigg(Given \: eq^n \bigg)$

• x = 3
• y = -2

Now, simply just plug in the value of x and y in equation (i) :

$:\implies\sf 3 \times 3 - 2 \times ( - 2) = k$

$:\implies\sf 9 - ( - 4) = k$

$:\implies\sf 9 + 4 = k$

$:\implies \underline{ \boxed{\sf 13 = k }}$

• Hence,the value of k is 13.
