It hase to be le letter c
-84 > -6(2 - 3b)
<em><u>Distributive property.</u></em>
-84 > -12 + 18b
<em><u>Add 12 to both sides.</u></em>
-72 > 18b
<em><u>Divide both sides by 18.</u></em>
-4 > b
The value of b is less than -4
Base or base number
for example 2^3 = 2 * 2 * 2 or x^2 = x * x
U can see the answer in the picture below

≥-4
Pretend the greater than or equal to sign is an equal sign, we will substitute it back in later.
x/2 = -4
Multiply both sides by 2 to get x alone
x = -8
Substitute the greater than or equal to sign back in and voila!
x≥-8
