Answer:

B has 1 fire truck

Step-by-step explanation:

Using the variable 'b' for the number of fire trucks that station B has, then you can use the following expression for the number of fire trucks that station A has:

A = 2b + 1 (one more than twice as many as B)

If fire station A has three fire trucks, you can set the expression above equal to 3:

3 = 2b + 1

Subtract 1 from both sides: 3 - 1 = 2b + 1 - 1 or 2 = 2b

Divide both sides by '2':  2/2 = 2b/2

Solve for 'b':  b = 1 fire truck
