Question

Solve 3x - 6=9 what is the answer?

Answer 1

x = 5

Explanation:

Step 1: Add both sides by 6:

(3x - 6 = 9) + 6

3x = 15

Step 2: Divide both sides by 3 to isolate and solve for x:

(3x = 15) / 3

x = 5

Optional Step 3: We can check that we've found the correct answer by plugging in 5 for x and checking that we get 9:

3(5) - 6 = 9

15 - 6 = 9

9 = 9
