rational equations and inequalities

Solve the equation below for b.

b space plus space 2 space equals space 8 over b

b = 4, b = 2

b = -4, b = -2

b = 4, b = -2

b = -4, b = 2

-----------------------------------------

Solve the equation for y.

fraction numerator 1 over denominator y space plus thin space 4 end fraction space equals space fraction numerator 2 over denominator y squared space plus space 3 y space minus space 4 end fraction space minus space fraction numerator 1 over denominator 1 space minus space y end fraction

y = -1/2

y = -1

y = 6

No solution

------------------------------------

Solve the equation for n.

fraction numerator 1 over denominator n space minus space 2 end fraction space equals space fraction numerator 2 n space plus thin space space 1 over denominator n squared space plus space 2 n space minus space 8 end fraction space plus thin space fraction numerator 2 over denominator n space plus space 4 end fraction

n = 7/3

n = -7/3

n = 11/3

n = -11/3

====================

Solve the inequality for b.

7 space minus space 2 over b space less than space 5 over b

b < 1

0 < b < 1

b < 0 or b > 1

b > -1

=========================

Solve the inequality for y.

fraction numerator 2 over denominator 3 y end fraction space plus space fraction numerator 5 over denominator 6 y end fraction space greater than thin space 3 over 4

y < 0 or y > 2

y > 2

0 < y < 2

y > 0

======================

Solve the inequality for b.

fraction numerator 12 over denominator b space minus space 1 end fraction space less than space 6

b < 1 or b > 3

1 < b < 3

b < 3

0 < b < 3

=======================

Solve the inequality for m.

fraction numerator 52 over denominator m space plus thin space 4 end fraction space greater than space 13

m < 0

m > 0

m < -4 or m > 0

-4 < m < 0

========================

The ratio of 3 more than a number to the square of 1 more than the number is less than 1. Find the numbers which satisfy this statement.

1 < n < 3

-2 < n < 1

n < -2 or n > 1

n < -1 or n > 1
