1 answer:
Answer:
w
Step-by-step explanation:
Monday = 4
Tuesday = 1/3 w (where w is the miles walked on Wednesday)
Wednesday = w
Total = 24
4 + 1/3 w + w = 24
Combine like terms
4 + 4/3 w = 24
Subtract 4 from each side
4/3 w = 20
Multiply each side by 3/4
w = 20 *3/4
w = 15
In the equation when we start, we need to put the variable, not the solution
At the end we have the solution
