The objective is to get the variable (x) alone. To do this start be subtracting 3. What you do to one side you have to do to the other so you have to subtract three from the other side of the equal sign as well. So now you have: 20x= 17-3 subtract the 3 to get 20x=14 Now because the 20 is attached to the x In order to get the x alone you have to divide by 20: 20x/20. =14/20 divide 14 by 20
Step-by-step explanation: First, we need to move all constants or variables other than x onto the other side of the equation. When a number crosses sides, its sign (- or +) changes to the opposite.
20x = 17 - 3
20x = 14
Now, we need to detach the 20 from the x. We can do this by dividing both sides of the equation by 20 (reversing the operation; the opposite of 20 · x is 20 · x ÷ 20).
After reflecting it, the square itself would not change, only the position of the square. Therefore, the same line segments from the beginning which were given would be parallel.
