Help can someone explain to me how this works and how do you solve for x? I would appreciate ;) <3

x=20

Step-by-step explanation:

When solving for a 5-sided pentagon we know the degrees add up to 540 degrees

Step 1: Write all variables given into an equation equal to 540 degrees

4x+5+7x+4x+10+6x+10+5x-5=540

I did not include the parenthesis because when I write out my equation they all share the same variable meaning they are like terms that can be combined.

Step 3: Combine like terms

26x+20=540

Step 4: Isolate the variable

By combining like terms like subtrating 20 to both sides. Always remember what you do to one side you must do to the other.

26x=540-20

Step 5:Continue to isolate the variable

26x=520

x=520/26

x=20

Final Answer

x=20 :) Hope that helped
