Question

What is the value of K, if(K, 5), is the solution of the simultaneous equations 4x+3y = 19 and 4x-3y=11?​

Answer 1

Answer:

The value of k is 1

Step-by-step explanation:

4k+15=19

4k-15=11

add 1 and 2

8k=8

k=1

I hope it will help you

Answer 2

Step-by-step explanation:

4 x + 3y = 19 (i)eq 4 x-3y = 11 eq(i)

(K,5)। x =k , y =5 is a solution --

satisfy both this equation

4K + 15 =19 4K - 15 = 11

4K = 19-15. 4k = 15-11

4K = 4 4K= 4

K=1 K=1

so answer is 1
