Question

Check whether (2,-2) is a solution of 2x- = 6

Answer 1

check it by putting the values in the given linear expression.

2(2)-(-2)=6

4+2=6 yest its true there for (2,-2) is the solution for given expression.

Answer 2

let p(x)=2x=6

2x-6=0

p(2)=2(2)-6=0

=4-6=0

-2=0

Hence 2 is not a solution of 2x=6

Now,

p(-2)=2(-2)-6=0

=-4-6=0

=-10=0

Therefore,

-2 is not a solution of2x=6
