Question

6 x - 5 = 3(7х-4)+7 пж

Answer 1

$6x - 5 = 3(7x - 4) + 7$

$6x - 5 = 21x - 12 + 7$

$6x - 21x = 7 + 5 - 12$

$- 15x = 0$

$x = \frac{0}{ - 15}$

$x = 0$

Answer 2

It seems like you have an equation to solve for the variable "x." Let's simplify and solve it step by step:

6x - 5 = 3(7x - 4) + 7

First, distribute the 3 on the right side of the equation:

6x - 5 = 21x - 12 + 7

Now, combine like terms on the right side:

6x - 5 = 21x - 5

Next, let's isolate the variable "x" on one side of the equation. You can do this by subtracting 6x from both sides of the equation:

6x - 6x - 5 = 21x - 6x - 5

This simplifies to:

-5 = 15x - 5

Now, add 5 to both sides of the equation:

-5 + 5 = 15x - 5 + 5

This simplifies to:

0 = 15x

Now, to isolate "x," divide both sides by 15:

0/15 = 15x/15

This simplifies to:

0 = x

So, the solution to the equation is:

x = 0
