Answer:
x=-4/3
Step-by-step explanation:
3x-12=12x
3x-12x=12
-9/-3=12/-3
then -3 cancels
3x/3=-4/3
then 3 cancels 3
so x=-4/3
X<9
The answer is x<9 because you first subtract 4 from both sides then divide both sides by -3. Which then would give you 9.
The first expression is equivalent to B
The second expression is equivalent to A
The third expression is equivalent to C
You are basically adding like terms. For example for the first expression, it is 7x^2 + 2x^2, which equals 9x^2. Remember since you're adding, do not add the exponents.
