Question

4) les on the graph x +2y=6, then find the value of a.
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)be x and y put the values in equation 2x+3y=4

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

2k-4+3k+3=4

5k-1=4

5k=4+1

5k=5

k=5/5

k=1
