Question

Tell whether the given value is a solution to the equation. (Yes or No) 2. 36 = 9×; x = 4 _______Show your work!

Answer 1

You have to prove if x=4 is a solution of the equation:

`36=9x`

To do so, you have to work with the term on the right side of the equation, that is, with "9x"

Replace x with 4 and solve the multiplication.

If the result is equal to 36, then x=4 is a solution of the equation.

If the result is not equal to 36, then x=4 is not a solution of the equation.

Replace 9x with x=4 and solve the multiplication:

`9x\to9\cdot4=36`

When you replace the equation with the given value of x, the result is 36. This means that

x=4 is a solution of the equation.
