Let r = # red flowers and w = # of white flowers.
5r + 8w = 76
r + w = 11
r = 11 - w
Substitute 11-w for r in the first equation to find w. Put that value in the second equation to find r. Check by putting both values in the first equation.
The flower peddler has red flowers with five petals each and white flowers with eight petals each. He has a total of 11 flowers with a total of 76 petals. How many red flowers are there and how many white flowers?
