Question

A cell boat sale has three sides that are all the same links. Each side measure x-10. The sails perimeter is 63 units

PLEASE HELP QUICKLY

Answer 1

x=31

Explanation:

x-10+x-10+x-10=63 (equation)

3x-30=63 (combine like terms)

3x=93 (combine like terms again)

x=31 (divide both sides by 3)
