Question

How do I solve this equation?
2|3x-3|=18

x=?

Answer 1

1. Divide both sides by 2
2. Think of two numbers which have 9 as their absolute value
3. Set 3x-3 equal to each number.
4. Solve both equations.

Answer 2

\(|3x-3|=9\)


crack on from there

Answer 3

i'd risk it and take the 3 out too

Answer 4

Divide both sides by 2.

2(|3x−3|)2=182
|3x−3|=9

Solve Absolute Value.

|3x−3|=9

We know either 3x−3=9or3x−3=−9

3x−3=9(Possibility 1)
3x−3+3=9+3(Add 3 to both sides)
3x=12
3x3=123(Divide both sides by 3)
x=4
3x−3=−9(Possibility 2)
3x−3+3=−9+3(Add 3 to both sides)
3x=−6
3x3=−63(Divide both sides by 3)
x=−2

Answer:

x=4 or x=−2
