Question

x+13= 17−x what step should I do ( what property)

Answer 1

To solve this equation, you should use the addition property of equality to isolate the variable on one side of the equation.

First, you can start by adding x to both sides of the equation in order to eliminate the -x on the right side:

x + x + 13 = 17 - x + x

This simplifies to:

2x + 13 = 17

Now you can use the subtraction property of equality by subtracting 13 from both sides in order to isolate the variable further:

2x + 13 - 13 = 17 - 13

This simplifies to:

2x = 4

Finally, to solve for x, you can divide both sides of the equation by 2, using the division property of equality:

2x/2 = 4/2

This simplifies to:

x = 2

So the solution to the equation is x = 2.
