Write the equation ​

Respuesta :

Answer:

5 hours

Step-by-step explanation:

Answer:

The equation is 4x + 10 = 30

then you solve for it and get that x =  5

Step-by-step explanation:

x is my number of hours the bike was in our possession

we solve for x

4x + 10 = 30

first subtract 10 from both sides

so now we have 4x = 20

now divide by 4 from both sides

now you have x = 5 and thats your answer
