In this video, Mr. J explains how to solve one-step subtraction equations involving negative numbers. The process is similar to solving equations with positive numbers, focusing on isolating the variable using inverse operations. Two examples are provided: solving J - 14 = -10 and 18 = G - (-3). The video emphasizes the importance of maintaining balance in equations by performing the same operation on both sides. It also highlights the concept of subtracting a negative as adding a positive. The video concludes with a recap of the methods discussed.

What is the first step in solving one-step subtraction equations with negatives?

• Divide both sides by the variable

• Subtract the same number from both sides

• Add the same number to both sides

• Multiply both sides by zero
