Marion is solving the equation 9 - 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)
As a first step, Marion adds 6 to both sides of the equation:
9 - 6 + 6 = 12 + 6
This simplifies to:
9 = 18
Now, Marion needs to divide each side by a certain value in order to solve the equation.
To find this value, we can divide both sides of the equation by 9:
9/9 = 18/9
This simplifies to:
1 = 2
Therefore, each side of the equation needs to be divided by 9 in order to solve the equation.
In the next step, each side needs to be divided by 3.
To solve the equation 9 - 6 = 12, Marion first adds 6 to both sides of the equation. This step is done to isolate the variable on one side of the equation.
So, after adding 6 to both sides, the equation becomes:
9 - 6 + 6 = 12 + 6
9 = 18
Now, in the next step, Marion needs to divide each side by a value to isolate the variable. To determine what value to divide each side by, you need to think about how the current equation can be simplified to solve for the variable.
In this case, since 9 is equal to 18, dividing each side of the equation by 9 will simplify the equation and give you the solution for the variable. Dividing by 9 cancels out the 9 on the left side, leaving just the variable, and it cancels out the 9 on the right side, simplifying the equation.
So, the value that each side needs to be divided by is 9.
