Question

Which equation doesn't belong? Explain your reasoning. 1. 1/4x = 27 2. 3x = 36 3. 3/4x = 9 4. 4x = 48

Answer 1

1/4x = 27

Explanation:

Given the equations :

1.)

1/4x = 27 ;

x/4 = 27

x = 27 * 4

x = 108

2.)

3x = 36

Divide both sides by 3

x = 36/3

x = 12

3.)

3/4x = 9

3x / 4 = 9

3x = 9*4

3x = 36

x =. 36/3

x = 12

4. 4x = 48

x = 48/4

x = 12

All other equations equal to 12 except (1)
