Question

Identify the equation that does not belong with the other three. Explain your reasoning. 5x = 20, 4b = 7, 8w = 32, 12y = 48

Answer 1

4b = 7

Explanation:

5x = 20 has solution x = 4

8w = 32 has solution w = 4

12y = 48 has solution y = 4

whereas 4b = 7 has solution b =
`(7)/(4)`

The other 3 equations have a solution of 4 making 4b = 7 the odd one out
