12(3-2x) = 84
do distributive multiplication:
12(3) + 12(-2x) = 84
36 - 24x = 84
Deduct 36 to both sides
36 - 36 - 24x = 84 - 36
-24x = 48
divide -24 to both sides
-24x / -24 = 48/-24
x = -2
To check:
12(3-2x) = 84
12(3-2(-2) = 84
12(3+4) = 84
12(7) = 84
84 = 84
X is a variable to find it you need to isolate it(get it by itself)

Branlist please!
Answer:
The correct answer is B. (2x and 7y)
Step-by-step explanation:
You cannot combine x to y therefore they are considered unlike terms .
Answer:
addition property of equality
Step-by-step explanation:
Given the equation 4(x-5) = -12
Expand
4x - 20 = -12
Add 20 to both sides (addition property of equality)
4x-20+20 = -12+20
4x = 8
x = 8/4
x = 2
Hence the value of x is 2
The justification for step 2 is addition property of equality
