Question

1) 3(х-2) - 3x + 7 - 3(х - 2x) = 0​

Answer 1

3x-6-3x+7-3x+6x=0

3x+1=0

3x=-1

x= -1/3

Answer 2

To solve the equation 3(x - 2) - 3x + 7 - 3(x - 2x) = 0, let's simplify the expression step by step:

First, distribute the multiplication: 3(x - 2) - 3x + 7 - 3(x - 2x) = 3x - 6 - 3x + 7 - 3(x - 2x)

Next, simplify the expressions inside the parentheses: = 3x - 6 - 3x + 7 - 3(x - 2x) = 3x - 6 - 3x + 7 - 3x + 6x

Combine like terms: = 3x - 3x - 3x + 6x - 6 + 7 = 3x - 3x - 3x + 6x + 1

Combine like terms again: = (3x - 3x - 3x + 6x) + 1 = 6x - 9x + 1 = -3x + 1

Now, the equation becomes: -3x + 1 = 0

To solve for x, let's isolate the variable x: -3x + 1 = 0 -3x = -1

Divide both sides by -3 to solve for x: x = (-1) / (-3)

Simplifying the expression on the right-hand side: x = 1/3

Therefore, the solution to the equation 3(x - 2) - 3x + 7 - 3(x - 2x) = 0 is x = 1/3.
