Question

Q8. If (k-2, k+1) is a solution of the equation 2x+3y=4, then find the value of k.​

Answer 1

Answer:

k=1

Step-by-step explanation:

(k-2 , k+1) this is a point of a graph.

What does a point of a graph look like? (x,y)

So we can replace (k-2) instead of x, and replace (k+1) instead of y:

2(k-2)+3(k+1)=4

multiply 2 by (k-2) and multiply 3 by (k+1).

2k-2+3k+1=4 and now just solve it.

5k-1=4 you have +1 both sides.

5k=5 then divide both sides by 5.

k=1
