−3(−2x−3)−3x+4=−2

1 answer

Let's solve the equation step by step:

Given: \[ -3(-2x - 3) - 3x + 4 = -2 \]

  1. Distribute \(-3\) on the left side: \[ -3 \cdot -2x + -3 \cdot -3 - 3x + 4 = -2 \] This simplifies to: \[ 6x + 9 - 3x + 4 = -2 \]

  2. Combine like terms on the left side: \[ (6x - 3x) + (9 + 4) = -2 \] This simplifies to: \[ 3x + 13 = -2 \]

  3. Now, isolate \(3x\) by subtracting 13 from both sides: \[ 3x = -2 - 13 \] This simplifies to: \[ 3x = -15 \]

  4. Divide both sides by 3 to solve for \(x\): \[ x = -5 \]

Thus, the solution to the equation is: \[ \boxed{-5} \]
