Question 141033
seven times the reciprocal of a number plus 2/3 is 3. Find the number
:
Let the number = x
:
{{{7/x}}} + {{{2/3}}} = 3
:
multiply equation by 3x to get rid of the denominators
3(7) + 2x = 3(3x)
21 + 2x = 9x
21 = 9x - 2x
21 = 7x
x = {{{21/7}}}
x = 3

:
check solution:
{{{7/3}}} + {{{2/3}}} = 3
