Question

How do you determine whether the pair (1,8) is a solution of y= 5+3x?

Answer 1

Answer:

Here x=1 and y=8

So, putting x=1 in the equation we get:   y=5+3*1  i.e  y=8

Hence the pair is a solution of the equation

Answer 2

check by putting values:-

8=5+3x

8-5=3x

3=3x

hence x =1

this when we put values of y it satisfies the value of 6 thus pair is correct solution...
