U/10 + U/5 = 6
1) Multipy by 10 ~> U + 2U = 60
2) Add common Variables ~> 3U = 60
3) Divide by 3 ~> U = 20
Therefor {20}

u/10 + u/5 = 6
first, combine like terms and use the properties of equality to get the variable on one side of the equals sign and the numbers on the other side. Remember to follow the order of operations.
1/5u + 1/6u = 6
add them...
3/10u = 6
multiply both sides by the reciprocal of the fraction.
u = 20
so, u is equal to 20. :)
