Help!! Please explain how you go it too please!!

The anwers is - the last equation, because having solved it, it is the same value :
x=-12
I hope I was of help ;)
2x = x - 6 - 6
2x = x - 12
2x - x = -12
x = -12
SIMPLER WAY
6 + 2x = x - 6
Subtract 6 from both sides;
2x = x - 12
2x - x = -12
x = -12
CHECK
6 + - 24 = -12 - 6
-18 = 18!
Therefore if you see one of my workouts it has 2x - x = 12 so the one at the very right (2x - x = 12) is the answer :)

The side lengths form a triangle that is similar to triangle ABC will be 30, 21, and 45. Option A is correct.
What is the triangle?
In terms of geometry, a triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
It is found that the sides of the triangle are,
AB=10
BC=7
CA=15
In order for the triangle to similar the ratio of their sides is equal.
AB:BC: CA = 10:7:15
The ratio is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
AB:BC: CA = 10×3:7×3:15×3
AB:BC: CA =30, 21, 45
The ratio of the triangle for the given condition must be the same.
Thus, the side lengths that form a triangle that is similar to triangle ABC will be 30, 21, and 45. Option A is correct.

Marcia is correct if she says she can use rounding to find the exact product of 6x75; the exact product of 6x75 must be halfway between 6x70 and 6x80.
What is an arithmetic operation?
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
It is given that:
Marcia says she can use rounding to find the exact product of 6x75.
From the data:
Find the product of 6 and 75:
= 6x75
= 450
Find the product of 6 and 70:
= 6x70
= 420
Find the product of 6 and 80:
= 6x80
= 480
= 420 + 30
=450
= 450 + 30
= 480
The expression can be defined as the combination of constants and variables with mathematical operators.
Thus, Marcia is correct if she says she can use rounding to find the exact product of 6x75; the exact product of 6x75 must be halfway between 6x70 and 6x80.

6x70=420
6x80=480
So 420+30=450
