Select a method that can be used to find the value x.

x - 18 = 6 - 3x

• Add x to both sides, subtract 6 from both sides, then divide both sides by 2.

• Add 3x to both sides add 18 to both sides, then divide both sides by 4.

• Subtract x from both sides, add 6 to both sides, then divide both sides by 4.

• Subtract 3x from both sides, subtract 18, then divide both sides by 2.
