Answer 3

Hello! It looks like you have an equation that needs to be solved. Let's simplify and solve it step by step.

The equation you provided is:

20x - 14x + 7x - 13 = 13

First, combine the like terms on the left-hand side of the equation:

(20x - 14x + 7x) - 13 = 13

Combine the x terms:

(20x - 14x + 7x) = 13 + 13

Now, add the x terms:

(20 - 14 + 7)x = 26

Combine the constants on the right-hand side:

13x = 26

Now, we want to isolate x on one side of the equation. To do that, divide both sides by 13:

x = 26 / 13

x = 2

So the solution to the equation is x = 2.

In the context of the 5th grade level, the equation's solution means that when x is equal to 2, the equation is true. You can verify this by substituting x with 2 in the original equation:

20(2) - 14(2) + 7(2) - 13 = 13

40 - 28 + 14 - 13 = 13

13 = 13

The equation is indeed true when x = 2.
