Question

1 solve the linear equation.
$9 - 4(3x + 1) = 3(6 - 3x) - 9$
$x = -1.3$

Explanation:

Step1: Expand both sides

$9 - 12x - 4 = 18 - 9x - 9$

Step2: Simplify both sides

$5 - 12x = 9 - 9x$

Step3: Rearrange terms to group $x$

$-12x + 9x = 9 - 5$

Step4: Combine like terms

$-3x = 4$

Step5: Solve for $x$

$x = \frac{4}{-3} = -\frac{4}{3}$

Answer:

$x = -\frac{4}{3}$ (or approximately $x \approx -1.33$)
