a 12-ft board i cut into 2 pieces so that one piece is 8 feet longer than 3 tines the shorter piece. If the shorter piece is x feet long, find the lengths

Question

of both pieces. How do i solve this step by step?

Answer 1

I will ignore the typing errors.
BTW...do you know what a tine is)?

 

let x = shorter measurement

longer = 3x+8.

 

Total = 12 ft and so you can add the two expressions for shorter & longer pieces to have an equation that you can solve.
