Answer:
x = 10
Step-by-step explanation:
x + x = 20 can also be interpreted as 2x = 20. This makes it easier to solve for the variable.
To isolate x, do the inverse operation of multiplication. So, we have to divide both sides of the equation by 2.
[tex]\frac{2x}{2}[/tex] = [tex]\frac{20}{2}[/tex]
Simplify this equation for x = 10.
I hope this is helpful. Good luck ^^
