Question

when ten is subtracted from the sum of a number 2/3 of the number and one fifth of the number the result is 102 find the 4/15 of the number

Answer 1

Answer: let n = the number

Step-by setp sum of 2/3 and five times a number is equal to 5/6 subtracted from six times the number.

2%2F3 + 5n = 6n - 5%2F6

multiply by 6 to get rid of the fractions

2(2) + 6(5n) = 6(6n) - 5

4 + 30n = 36n - 5

30n + 4 = 36n - 5

4 + 5 = 36n - 30n

9 = 6n

n = 9/6
