Question

Given the equation 5X-10=50 which properties will be used to solve for XA. Adition and subtractionB. Subtraction and divisionC. Adition and division D. Subtraction and Multiplication

Answer 1

Let's solve for x and see what properties are used

First, add 10 to both sides of the equation

`\begin{gathered} 5x-10=50 \\ 5x-10+10=50+10 \\ 5x=60 \end{gathered}`

Now, divide by 5 on both sides of the equation

`\begin{gathered} (5x)/(5)=(60)/(5) \\ x=12 \end{gathered}`

Therefore, the correct answer is C. Adition and division
