x+13= 17−x what step should I do ( what property)
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.
To solve the equation x + 13 = 17 - x, you will want to use the commutative property of addition. This property states that you can add or subtract terms in any order without changing the result.
To apply the commutative property in this equation, you can rearrange the equation by moving the x term to the same side as the x term, and the constant terms to the other side. The equation will then be:
x + x = 17 - 13
Simplifying this further, the equation becomes:
2x = 4
By using the commutative property, you have simplified the equation to its next step.
To solve the equation x + 13 = 17 - x, we need to isolate the variable 'x' on one side of the equation.
Step:
1. Start by adding 'x' to both sides of the equation to eliminate the variable on the right side:
x + x + 13 = 17 - x + x
This simplifies to:
2x + 13 = 17
The property used in this step is the Addition Property of Equality, which states that if you add the same number to both sides of an equation, the equality still holds.
