The planet Uranus has 13 more moons than Neputune, Saturn has 2 more than twice the number of moons of Neptune. The total number of moons for these planets is 47. How many moons does each planet have?
Let Neptune have x moons
uranus has x+13 moons
saturn has 2x+2
Total moons =47
..
x+x+13 +2x+2=47
4x+15=47
4x=32
x=8
..
Neptune has 8 moons
Uranus has 8+13 = 21 moons
Saturn has 2x+2 = 18 moons
..
CHECK
8+18+21=47
