Answer: 5

Step-by-step explanation:

To solve this equation, you would divide 8 by both sides of the equation to isolate the y variable. this would leave you with the the answer y = 5. To check this solution, you would simply do the reverse operation (multiply 5 by 8). Since multiplying 8×5 = 40, the answer is correct :)

Solving the equation, 40 = 8y, the solution is 5. Substituting y = 5 into the equation to check the solution will give us 40 = 40, which means the solution is correct.

How to Check the Solution to an Equation

  • After solving an equation to determine the value of a variable, plug in the value of the variable into the equation.
  • If the solution is correct, the right side will be equal to the left side of the equation.

Given:

40 = 8y

Divide both sides by 8

5 = y

y = 5

Check the Solution: Plug in the value of y into 40 = 8y

40 = 8(5)

40 = 40 (True).

Thus, solving the equation, 40 = 8y, the solution is 5. Substituting y = 5 into the equation to check the solution will give us 40 = 40, which means the solution is correct.
