To "undo" the equation and solve for t, Tim will need to perform two inverse operations:
1. Subtracting 18 from both sides of the equation: This will undo the addition of 18 to the left side of the equation, leaving 3t isolated on the left side. The equation becomes 3t = -39 - 18.
2. Dividing by 3 on both sides of the equation: This will undo the multiplication of 3 to the t term, isolating t on the left side of the equation. The equation becomes t = (-39 - 18) / 3.
Therefore, to solve for t, Tim needs to subtract 18 from both sides of the equation and then divide both sides of the equation by 3.
Tim is solving this linear equation. He will need to perform two inverse operations. What inverse operations will he need to do to "undo" the equation to solve for t?
3t + 18 = - 39
