Could Anyone Show Me The Steps In How To Solve This Algebra Problem? 3(2x-4)=3x-(5-x)

How do I solve this problem?

3 X n = 2

X2-12x-27=0

Solve using the zeros or intersect method 4x^2+12x-27=0

3 girls are traveling on a bus, each girl is holding 3 baskets in each hand, in each basket there are 3 cats each cat has 3 little kittens, one of the girls is getting off the bus how many legs are there in the bus?

Simplifying
3(2x + -4) = 3x + -1(5 + -1x)

Reorder the terms:
3(-4 + 2x) = 3x + -1(5 + -1x)
(-4 * 3 + 2x * 3) = 3x + -1(5 + -1x)
(-12 + 6x) = 3x + -1(5 + -1x)
-12 + 6x = 3x + (5 * -1 + -1x * -1)
-12 + 6x = 3x + (-5 + 1x)

Reorder the terms:
-12 + 6x = -5 + 3x + 1x

Combine like terms: 3x + 1x = 4x
-12 + 6x = -5 + 4x

Solving
-12 + 6x = -5 + 4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4x' to each side of the equation.
-12 + 6x + -4x = -5 + 4x + -4x

Combine like terms: 6x + -4x = 2x
-12 + 2x = -5 + 4x + -4x

Combine like terms: 4x + -4x = 0
-12 + 2x = -5 + 0
-12 + 2x = -5

Add '12' to each side of the equation.
-12 + 12 + 2x = -5 + 12

Combine like terms: -12 + 12 = 0
0 + 2x = -5 + 12
2x = -5 + 12

Combine like terms: -5 + 12 = 7
2x = 7

Divide each side by '2'.
X = 3.5

Simplifying
x = 3.5

The problem can be solved for the value of x as follows;

3(2x-4)=3x-(5-x)
6x-12=3x-5+x
6x-12=4x-5
6x-4x=12-5
2x=7
x=7/2
x=3.5 is the answer.
