John needs to plant a 50-acre field. He wants to use a total of 2,000 pounds of seed for the entire field. The equation for this situation is given below, where x represents the number of pounds of seed he should plant on each acre.

50x = 2000

If John plants the field in a uniform manner, how many pounds of seed will he need to plant per acre?
x=
