it means that x should equal 10. x + x = 20. x = 10
1 x 260, 2 x 130, 4 x 65, 5 x 52, 10 x 26, 13 x 20.
-13/20 x=5 solution
15 x 13 x 12 is equal to 2,340
13 x 20 = 260 square feet (13 and 20 must be in feet)
13 x 13 x 13 is equal to 2,197
7 + 13 = 20 Note that there are no two prime numbers x and y that multiply to 20.
13 x 13 x 13 = 2197

18.5 x 13 = 240.5
13 x 379 = 4927
-13/20 x=5 solution
Well, 26 is the only single number equal to itself, but you could combine numbers to get there... like 13 x 2, or 20 + 6, or 260 divided by ten.
13 x 20 = 260 square feet (13 and 20 must be in feet)
15 x 13 x 12 is equal to 2,340
1 x 169, 13 x 13 = 169
