You can put this solution on YOUR website! let x = "a number"
:
Write an equation for the statement:
"the sum of the reciprocal of a number and the reciprocal of 3 less that the number 5 time the reciprocal of the original number." + + 3 = 5()
multiply by 3x, results
1(3) + 1(x) + 3(3x) = 3(5)
:
3 + x + 9x = 15
10x = 15 - 3
10x = 12
x = 12/10
x = 1.2
