Answer:
[tex]x=\frac{4}{3}[/tex]
Step-by-step explanation:
[tex]-\left(3x-12\right)=9x-4[/tex]
Distribute the negative sign to both 3x and -12:
[tex]-\left(3x\right)-\left(-12\right)=9x-4[/tex]
Remove brackets: (Double negative = Positive)
[tex]-3x+12=9x-4[/tex]
Subtract 12 from both sides:
[tex]-3x+12-12=9x-4-12[/tex]
[tex]-3x=9x-16[/tex]
Subtract 9x from both sides:
[tex]-3x-9x=9x-16-9x[/tex]
[tex]-12x=-16[/tex]
Divide both sides by -12:
[tex]\frac{-12x}{-12}=\frac{-16}{-12}[/tex]
[tex]x=\frac{4}{3}[/tex]
