Alex had 4 cakes. he gives his friend 3, how many does he have?

Alex has 1 cake

Step-by-step explanation:

I mean pretty simple subtraction here, it's 4-3=1. That's finger math dude

tiene  1

Step-by-step explanation:

ya que como dice  tenia es decir que regalo es una simple resta 4-3 igual 1

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
