To solve these kinds of problems, it is necessary to isolate x:
9(2x + 1) <span>< 9x - 18
Distribute 9:
18x + 9 </span><span>< 9x - 18
Subtracting 9 from both sides of the equation:
18x + 9 - 9 </span><span>< 9x - 18 - 9
18x </span><span>< 9x - 27
Subtracting 9x from both sides of the equation:
18x - 9x </span><span>< 9x - 27 - 9x
9x </span><span>< -27
x </span><span>< -3
Therefore, values of x </span><span>< -3 will satisfy the given equation.</span>

Answer:
> -5 4/5 is greater than
Step-by-step explanation:
First you must make them have the same denominator. So you think, which numbers do 5 and 16 have in common. 5, 10, 15 , 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80...... 16, 32, 48, 64, 80. We see that they have the number 80 in common so we multiply 4/5 by 16 which equals 64/80 then we multiply 3/16 by 5 which equals 15/80 we now see the new equation which is: -5 64/80 ___ -5 15/80. we see that -5 64/80 is greater
