Question

Explain how to solve the equation and how to check the solution.
40 = 8y

Answer 1

Answer:

5

Step-by-step explanation:

40=8y

8y=40

so y=40÷8

y=5

Answer 2

Answer:

Use the inverse operation to isolate the variable. Undo multiplication by dividing by 8 on both sides of the equation. Simplify by completing the divisions, 40 ÷ 8 = 5, and 8 ÷ 8 = 1. The solution is y = 5. Check the solution by substituting 5 for y in the original equation, and then simplify. 8 × 5 = 40 and 40 = 40 is a true statement, so 5 is the solution.
