Study Notes
Solving the Equation -3(x+6) = 12
- The equation -3(x+6) = 12 is solved by multiplying the terms inside the parentheses by -3, resulting in -3x - 18 = 12.
- The next step is to add 18 to both sides of the equation, resulting in -3x = 30.
- Finally, dividing both sides of the equation by -3 results in x = -10.
- The friend's solution, x = -2, is incorrect.
Friend's Mistakes
- The friend multiplied both sides of the equation by -3, resulting in -3x = 12.
- However, the friend did not fully solve for x, resulting in an incorrect solution.
- The correct steps to solve the equation were not followed, leading to an incorrect answer.
