Answer:
x = 7
Step-by-step explanation:
Step 1: Add 6 to both sides.
- [tex]3x - 6 + 6 = 15 + 6[/tex]
- [tex]3x = 21[/tex]
Step 2: Divide both sides by 3.
- [tex]\frac{3x}{3} = \frac{21}{3}[/tex]
- [tex]x = 7[/tex]
Step 3: Plug in the value to see if it's correct.
- [tex]3(7) - 6 = 15[/tex]
- [tex]21 - 6 = 15[/tex]
- [tex]15 = 15[/tex]
Therefore, x = 7.
