3(−3x−1)+5x+4=−15

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

1. Distribute the 3 in the first term on the left side of the equation: 3 * -3x = -9x and 3 * -1 = -3. So, the equation becomes -9x - 3 + 5x + 4 = -15.

2. Combine like terms on the left side of the equation: -9x + 5x = -4x and -3 + 4 = 1. So, the equation becomes -4x + 1 = -15.

3. Subtract 1 from both sides of the equation to isolate the x term on the left side: -4x = -15 - 1, which simplifies to -4x = -16.

4. Divide both sides of the equation by -4 to solve for x: x = -16 / -4, which simplifies to x = 4.

So, the solution to the equation 3(-3x - 1) + 5x + 4 = -15 is x = 4.
