Question

if (2,-5) is the solution of the equation 2x-ky= 14
the find K=?​

Answer 1

Answer:

k=2

Step-by-step explanation:

You plug in 2 for x and -5 for y, after this you get 4-(-5*k)=14. Subtract 4 from both sides and you get -(-5*k)=10. Since the negative in front is the same as multiplying by -1 so -1*-5*2=10
