Find the value of k, if x = - 4, y = - 5 is a solution of the equation: 3x - 4y = K

• K = 6

• K = - 6

• K = 8

• K = - 4

Answer explanation

3x - 4y = K Substituting x = - 4 and y = - 5 in the equation, we get, 3(- 4) - 4(- 5) = K - 12 + 20 = K K = 8 Therefore, the value of K = 8

Find the value of k if (-4, -5) is a solution of the equation: 3x - 4y = K

• K = 6

• K = - 6

• K = 8

• K = - 4

Answer explanation

3x - 4y = K Substituting x = - 4 and y = - 5 in the equation, we get, 3(- 4) - 4(- 5) = K - 12 + 20 = K K = 8 Therefore, the value of K = 8
