Question

Is b = 15 a solution to the equation 4b - 20 = 40?

yes

no


WICH ONE

Answer 1

Yes

Explanation:

4 x 15 = 60. 60 - 20 = 40

Answer 2

Answer: yes

Here, we want to decide if 15 is a solution for the equation 4b - 20 = 40. We can do this by simply plugging in 15 for b. If the statement holds true when 15 is plugged in for b, then 15 is a solution.

Plugging in 15 for b, we have 4(15) - 20 = 40.

4(15) is equal to 60.

So we have 60 - 20 = 40 or 40 = 40.

Since the statement holds true, yes,

15 is a solution for the equation.
