Simplifies, a is odd, b is even

Simplifies, a + b = 9

Does not simplify, even and odd

Equivalent to 2:3, b = 12

Simplifies, a = 21

5x – 2 < 7, x > -4, x-squared = 25

y > 2x + 1, x + y < 1, y < x - 1

y < x, x + y < 8, x > 0

y < 2x, y < 6, x > 1

x < 7, 2x + 7 > 10, x is an integer

y > x, x + y > 1

x + y < 10, y > 2x

x + 2 < 10, 8 - x > 3

x > 5, 2x < 14

x < 9, x > 3

Smaller than 4/5, bigger than 0.7, ends in a 2

Bigger than 1/3, smaller than 40%, 3 digits long

Bigger than 70%, smaller than 0.8, denominator is 20

Bigger than 0.15, smaller than 1/4
