Question

what is the value of K. (K,5) is the soultion of the
Simaltaneous equation 4x+3y=19 and 4x-3y =-11​

Answer 1

Answer:

x is equal to k so

4x + 15=19

x=4/4=1 k = 1

Answer 2

Step-by-step explanation:

4x+3y=19 ☞ eqn 1

4x-3y=-11 ☞ eqn 2

Solve eqn 1 and 2

4x+3y=19

(-)4x-3y=-11

(=)8x+0=8

☞ 8x=8

☞ X=8/8

☞ X=1

In (K,5), K is the X coordinate. As X=1, the value of k is 1.
