Answer 2

Answer:

$\Large\boxed{X=3}$

Step-by-step explanation:

GIVEN:

3(3x - 5) = 12

To solve this problem, first you have to isolate by the x on one side of the equation.

SOLUTIONS:

First, you have to divide by 3 from both sides.

$\displaystyle \frac{3(3x-5)}{3}=\frac{12}{3}$

Solve.

Divide numbers from left to right.

$\displaystyle 12\div3=4$

$\displaystyle 3x-5=4$

Next, you add by 5 from both sides.

$\displaystyle 3x-5+5=4+5$

Solve.

Add the numbers from left to right.

$\displaystyle 4+5=9$

$\displaystyle 3x=9$

Then, you divide by 3 from both sides.

$\displaystyle \frac{3x}{3}=\frac{9}{3}$

Solve. (Solution/Simplify/Refine.)

Divide.

$\displaystyle 9\div3=\boxed{3}$

$\Large\boxed{X=3}$

In conclusion, the final answer is x=3.
