Question

If x = 4 and y = 3 is a solution of the equation 4x – 3y = k, find the value of k *

Answer 1

$k = 7$

Step-by-step explanation:

$Given, \: \: \: equation \: \: \: 4x-3y=k \: \: \: and \\ solution \: \: \: x=4 \: \: and \: \: y=3 \\ Now, \: \: \: putting \: \: values \\ 4 \times 4 - 3 \times 3 = k \\ 16 - 9 = k \\ 7 = k \\ \boxed{ k = 7}$
