Question

Identify the equation that dose not belong with the other three explain your reasoning pls

Answer 1

4b=7 does not belong because 4 times something does not equal 7

Answer 2

If you take a moment and solve each equation (find the value
of the letter in each one), it'll jump out at you.

Here, let me do it for you.  Why should you tire yourself.

5x = 20 . . . . . x = 4

4b = 7 . . . . . . b = 7/4

8w = 32 . . . . . w = 4

12y = 48 . . . . . y = 4

The second equation is not like the others.
It's the only one where the letter is not equal to  4 .
