Question

5 [-x] -2 [-x] = 18 (решите уравнение)

Answer 1

5х-2х=18

3х=18

х=18/3

х=6

Answer 2

To solve the equation, we need to find the value of "x" that satisfies the equation:

5[-x] - 2[-x] = 18

Let's simplify the expression step by step:

1. Distribute the coefficients inside the brackets: 5 * -x - 2 * -x = 18

2. Simplify the equation by combining like terms: -5x + 2x = 18

3. Combine the "x" terms on the left side: -3x = 18

4. Now, isolate "x" by dividing both sides of the equation by -3: x = 18 / -3

Finally, calculate the value of "x": x = -6

So, the solution to the equation is x = -6.
