7x+28=7x-15

28=-15

х=0

Answer 3

To solve the equation 7(x + 4) = 7x - 15, we can start by simplifying both sides of the equation:

7(x + 4) = 7x - 15

Let's distribute the 7 on the left side:

7x + 7(4) = 7x - 15

Simplify the left side:

7x + 28 = 7x - 15

Next, we want to isolate the variable terms on one side of the equation. We can do this by subtracting 7x from both sides:

7x - 7x + 28 = 7x - 7x - 15

Simplify:

28 = -15

Now we can see that the equation is inconsistent. The left side of the equation is 28, while the right side is -15. Since these values are not equal, there is no solution to the equation.
