Answer 2

Ответ:

-5(x+3)-12=-1(x+13)+16

-5x-15-12=-(x+13)+16

-5x-27=-x-13+16

-5x-27=-x+3

-5x+x=3+27

-4x=30

Answer 3

To solve the equation -5(x + 3) - 12 = -1(x + 13) + 16, you'll need to follow these steps:

1. Distribute the constants outside the parentheses to the terms inside the parentheses.

-5(x + 3) = -5x - 15 -1(x + 13) = -x - 13

So the equation becomes:

-5x - 15 - 12 = -x - 13 + 16

2. Now, combine like terms on both sides of the equation:

-5x - 27 = -x + 3

3. Next, we want to isolate the x terms on one side of the equation and the constant terms on the other side. To do this, you can add 5x to both sides and add 27 to both sides:

-5x + 5x - 27 + 27 = -x + 5x + 3 + 27

This simplifies to:

0 = 4x + 30

4. Now, subtract 30 from both sides to isolate the 4x term:

0 - 30 = 4x + 30 - 30

-30 = 4x

5. Finally, divide both sides by 4 to solve for x:

-30 / 4 = 4x / 4

-7.5 = x

So, the solution to the equation is:

x = -7.5
