Given:
The cost price of two pieces of equipment was $2000.
The cost price of one is $770 more than the other.
To find the price of the less expensive piece of equipment:
Let x be the price of the less expensive piece of equipment.
That is, x+770 is the price of the other piece of equipment.
So, we write it as,
[tex]\begin{gathered} x+x+770=2000 \\ 2x=1330 \\ x=665 \end{gathered}[/tex]So, the price of the less expensive piece of equipment is $665.
