Question

MEDAL FOR CHECKING-- Is it A ?

Answer 1

It is not A :)

The goal here is to make sure that both sides are equal once you plug in the variable

Answer 2

see how the two sides given equal 15? the two other sides should also be equivalent

Answer 3

you can check this by plugging in the value for the variable.

2x-9
x+8

2(15) -9
(15) +8

=21
=23

\(21\ne23\)

Answer 4

when plugging in "15" for the two equations, the numbers aren't equal. As soon as you find a number that makes both sides equal in value, that'll be your correct answer :)
