First distribute the 3 so you'll have:
12+12x=12x+12
Next you subtract 12 from both sides and you'll get:
12x=12x
then you divide both sides by 12 and you get:
x=x
Problem: 3(4+4x)=12x+12
The first thing that you need to do is distribute 3(4+4x).
Subtract 12x from both sides.
12=12
This means that the equation has infinitely many solutions.
I hope this helps you :)
Plz mark me as brainliest if this helped :)
Answer:
15.4 is the range.
Step-by-step explanation:
since there is no decimal, the answer is 8,690,000.0 (the tenth place is one place after the decimal)
x = 20
The two angle are a linear pair. Their measures has a sum of 180 deg.
2x + 140 = 180
2x = 40
