difference of the number and 1 isequal to six times the reciprocal of the
difference of the number squared and 1.
Replace "five" by "5", and "six" by "6"
5 divided by the sum of a number and 1, minus the quotient of 3 and the
difference of the number and 1 is equal to 6 times the reciprocal of the
difference of the number squared and 1.
Replace the words "a number" and "the number" by "x"
5 divided by the sum of x and 1, minus the quotient of 3 and the
difference of x and 1 is equal to 6 times the reciprocal of the
difference of x squared and 1.
Replace "the sum of x and 1" by "x+1"
5 divided by x+1, minus the quotient of 3 and the
difference of x and 1 is equal to 6 times the reciprocal of the
difference of x squared and 1.
Replace "the difference of x and 1" by "x-1"
5 divided by x+1, minus the quotient of 3 and x-1 is equal to
6 times the reciprocal of the difference of x squared and 1.
Replace "the difference of x squared and 1" by "x²-1"
5 divided by x+1, minus the quotient of 3 and x-1 is equal to
6 times the reciprocal of x²-1.
Replace "5 divided by x+1" by "5/(x+1)
5/(x+1) minus the quotient of 3 and x-1 is equal to
6 times the reciprocal of x²-1.
Replace "the quotient of 3 and x-1" by "3/(x-1)"
5/(x+1) minus 3/(x-1) is equal to
6 times the reciprocal of x²-1
Replace "the reciprocal of x²-1 by 1/(x²-1)
5/(x+1) minus 3/(x-1) is equal to
6 times 1/(x²-1)
Replace "6 times 1/(x²-1)" by "6/(x²-1)
5/(x+1) minus 3/(x-1) is equal to
6/(x²-1)
Replace the word minus by "-", and "is equal to" by "="
5/(x+1) - 3/(x-1) = 6/(x²-1)
Can you solve that?
5 3 6
——— - ——— = ————
x+1 x-1 x²-1
Factor the denominator on the right:
5 3 6
——— - ——— = ——————————
x+1 x-1 (x-1)(x+1)
Multiply through by the LCD of (x-1)(x+1)
5(x-1) - 3(x+1) = 6
5x - 5 - 3x - 3 = 6
2x - 8 = 6
2x = 14
x = 7
