Marion is solving the equation 9x − 6 = 12 . As a first step, she adds 6 to both sides of the equation. In the next step, by what value does each side need to be divided? (1 point)
___
By dividing both sides by 9
To solve the equation 9x - 6 = 12, Marion added 6 to both sides of the equation. This step helps isolate the variable x on one side of the equation.
The equation now becomes:
9x - 6 + 6 = 12 + 6
Simplifying further,
9x = 18
To isolate x, we need to divide both sides of the equation by the coefficient of x, which is 9.
Dividing both sides by 9, we get:
(9x)/9 = 18/9
Simplifying further,
x = 2
Therefore, each side needs to be divided by 9 to solve the equation.
