Question

X — 3(х+1) = 2(3x — 2) +7x — 3х — 3=6x — 4 + 7х-3х — 6x=3 — 4 + 7​

Answer 1

Ответ:

Х-3(х+1)=2(3х-2)+7

Х-3х-3=6х-4+7

-2х-3=6х+3

-2х-6х=3+3

-8х=6

Х= - 6/8= - 3/4

Answer 2

It looks like you're trying to solve a linear equation. Let's break down the equation step by step to simplify and solve for the value of x.

Starting with the given equation: X - 3(x + 1) = 2(3x - 2) + 7x - 3x - 3

First, apply the distributive property (also known as the distributive law) to both sides of the equation:

X - 3x - 3 = 6x - 4 + 7x - 3x - 3

Now, let's combine like terms on each side of the equation:

On the left side: X - 3x simplifies to -2x.

On the right side: 6x + 7x - 3x simplifies to 10x. -4 - 3 simplifies to -7.

Now, our equation becomes:

-2x = 10x - 7

Next, we want to isolate the variable x. To do that, we'll move the terms involving x to one side of the equation and the constant to the other side. Let's add 2x to both sides:

-2x + 2x = 10x - 7 + 2x

This simplifies to:

0 = 12x - 7

Now, add 7 to both sides to isolate the term with 12x:

0 + 7 = 12x - 7 + 7

This simplifies to:

7 = 12x

Finally, to solve for x, divide both sides by 12:

7 / 12 = 12x / 12

7/12 is the simplified value for x:

x = 7/12

So, the solution to the equation is:

x = 7/12
