3(−2x−1)+x−2=25

Sure, let's solve the equation step by step:

1. Distribute the 3 to both terms inside the parentheses: 3 * -2x and 3 * -1. This gives us -6x - 3.

2. So, the equation now is -6x - 3 + x - 2 = 25.

3. Combine like terms on the left side of the equation: -6x + x gives us -5x, and -3 - 2 gives us -5. So, the equation now is -5x - 5 = 25.

4. Add 5 to both sides of the equation to isolate the x term on the left side. This gives us -5x = 30.

5. Finally, divide both sides of the equation by -5 to solve for x. This gives us x = -6.
