Answer:
x = - [tex]\frac{26}{3}[/tex]
Step-by-step explanation:
3(4x - 12) + 3 = 3x - 7 + 12x ← distribute parenthesis and simplify left side
12x - 36 + 3 = 15x - 7
12x - 33 = 15x - 7 ( subtract 15x from both sides )
- 3x - 33 = - 7 ( add 33 to both sides )
- 3x = 26 ( divide both sides by - 3 )
x = - [tex]\frac{26}{3}[/tex]
