Answer 1

Ответ:

7х+1-9х-3=5

-2х-2=5

-2х=7

Х=-3,5

Answer 2

7х+1-9х-3=5
-2х-2=5
-2х=5+2
-2х=7
х= -3,5

Answer 3

To solve the equation (7x + 1) - (9x + 3) = 5, you'll need to perform the operations to isolate the variable x. Here are the steps:

1. Distribute the negative sign in front of the parentheses on the left side of the equation:

   7x + 1 - 9x - 3 = 5

2. Combine like terms on the left side of the equation:

   (7x - 9x) + (1 - 3) = 5

   -2x - 2 = 5

3. Add 2 to both sides to isolate the -2x term on the left side:

   -2x - 2 + 2 = 5 + 2

   -2x = 7

4. Finally, divide both sides by -2 to solve for x:

   -2x / -2 = 7 / -2

   x = -7/2

So, the solution to the equation (7x + 1) - (9x + 3) = 5 is:

x = -7/2
