Ответ: 15

Answer 2

-15-3x=-7x+45
-3x+7x=45+15
4x=60
x=15

Answer 3

To solve the equation -15 - 3x = -7x + 45, we'll start by simplifying and rearranging the equation to isolate the variable x on one side.

First, let's combine like terms on both sides of the equation:

-15 - 3x = -7x + 45

We can simplify -15 and bring the variables to one side:

-3x + 7x = 45 + 15

Combine the x terms:

4x = 60

Now, to isolate x, we divide both sides of the equation by 4:

4x/4 = 60/4

x = 15

Therefore, the solution to the equation -15 - 3x = -7x + 45 is x = 15.
