х=-2

Answer 2

To solve the equation, we need to isolate the variable x on one side. Let's do that step-by-step:

1. Start by moving all terms containing x to one side of the equation and constants to the other side: 5x + 7 = x - 1

2. To move x to one side, subtract x from both sides of the equation: 5x - x + 7 = x - x - 1

3. Simplify the equation: 4x + 7 = -1

4. Now, move the constant term (7) to the other side of the equation by subtracting 7 from both sides: 4x + 7 - 7 = -1 - 7

5. Simplify the equation further: 4x = -8

6. Finally, isolate x by dividing both sides by the coefficient of x (which is 4): 4x/4 = -8/4

7. Simplify: x = -2

So, the solution to the equation is x = -2.
