Question

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

Answer 1

The answer is 5!

Explanation:

To do this, we have to solve the equation.

8 × y = 40 [ 8 multiplied with a no. gives 40]

To know the value of the variable 'y' we have to divide 40 by 8 by transporting 8 to the Right hand side of the equation.

y = 40 ÷ 8

= 5

Answer 2

y = 5

solve:

`\sf 40 = 8y`

`\sf 8y = 40`

`\sf y = (40)/(8)`

`\sf y = 5`

check:

`\sf 8(5) = 40`

`\sf 40 = 40`

note: changing sides, changes sign multiplication to division and vice versa.
