Question

2x : 3 = ( x - 1 ) : 6​

Answer 1

По правилу пропорции получаем

2x*6=3(x-1)
12x= 3x-3
12x-3x=-3
9x=-3
X = -3/9
X= -1/3

Answer 2

Let's solve the given equation step by step:

2x : 3 = (x - 1) : 6

First, let's cross-multiply to get rid of the fractions:

2x * 6 = 3 * (x - 1)

12x = 3x - 3

Now, let's isolate the variable x by moving the terms involving x to one side and the constant terms to the other side:

12x - 3x = -3

9x = -3

Now, divide both sides by 9 to solve for x:

x = -3 / 9

x = -1/3

So, the solution to the equation is x = -1/3.
