Question

(7x+1) - (9x+3) = 11;

Answer 1

Пошаговое объяснение:

(7x+1) - (9x+3) = 11;

7х-1-9х-3=11

-2х=15

х=-7,5

Answer 2

To solve the equation (7x + 1) - (9x + 3) = 11, follow these steps:

1. First, distribute the negative sign on the left side of the equation:

(7x + 1) - 9x - 3 = 11

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

(7x - 9x) + (1 - 3) = 11

3. Simplify the equation further:

-2x - 2 = 11

4. Now, isolate the variable x by moving the constant term (-2) to the other side of the equation. To do this, add 2 to both sides of the equation:

-2x - 2 + 2 = 11 + 2

-2x = 13

5. Finally, solve for x by dividing both sides by -2:

(-2x) / (-2) = 13 / (-2)

x = -13/2

So, the solution to the equation (7x + 1) - (9x + 3) = 11 is:

x = -13/2 or x = -6.5
