Question

Check which of the following are solutions of the equation 4x – 2y = 8 and which are not: (i) (3, 2) (ii) (2, 0) (iii) (4,0)

Answer 1

Step-by-step explanation:

(i) By using x=3 and y=2

4(3)-2(2)=8

So, it's a solution.

(ii) By using x=2 and y=0

4(2)-2(0)=8

So, it's a solution

(iii) By using x=4 and y=0

4(4)-2(0)=16 which is not equal to 8

So, it's not a solution.

I hope this helped, lemme know if I'm incorrect.
