Question

Devon has 14 steel balls of equal weight. If he puts 8 of them in one pan of a balance, and the rest along with a weight of 20 grams in the other pan, the pans balance each other. Which equation can be used to find the weight of each steel ball?
A)
8x = 26x
B)
8x = 120x
C)
8x + 20 = 6x
D)
8x = 6x + 20

Answer 1

an equation means
you have 2 sides that are equal (or balance each other)

If he puts 8 of them in one pan

then you might expect
8 something =


the rest along with a weight of 20 grams in the other pan
if 8 are in one pan, how many are left over to go in the other pan
what do you think goes on the other side of
8 something =
?
