Let 'x' represent the number of beads needed to make a necklace of 35 beads.
Kenya has 28 and she needs x more so that she has total of 35 beads:
28 + x = 35
x = 35 - 28
x = 7 beads
Kenya needs 7 beads more to make the necklace.
Nancy has 25 and she needs x more so that she has total of 35 beads:
25 + x = 35
x = 35 - 25
x = 10 beads
Nancy needs 10 beads more to make the necklace.
