Susie

Amelia

2x - 3 = 4x - 2

2x - 3 = 4x - 2

2x - 2x - 3 = 4x - 2x - 2

2x - 3 + 3 = 4x - 2 + 3

-3 = 2x - 2

2x = 4x + 1

-3 - 2 = 2x

2x - 4x = 4x - 4x + 1

-5 = -2x

-2x = 1

negative two x divided by negative two equals negative four divided by negative two

negative eight divided by two equals two x divided by two

negative five over two = x

x = negative one half
