Question

3x + 2y = 5

5x + 2y = 7
Based on the given system of equations, which of the following is not true?

Answer 1

3x + 2y = 5
5x + 2y = 7
(eliminate the equation)

-2x = -2

x = 1 . . . .(put x in equation and you will get that y is also 1)

So the one that is not true is the one where x and y is not 1, like :
8x = 12

Hope this helps
