Solving Two-Step Equations

The video tutorial explains how to solve the equation x/2 + 4 = 3 by isolating the variable x. It covers the process of solving two-step equations, emphasizing the importance of understanding each step. The solution involves subtracting 4 from both sides and then multiplying by 8 to find that x equals -8. The solution is verified by substituting back into the original equation.

What is the initial equation presented in the video?

• x divided by 3 plus 4 equals 2

• x divided by 2 plus 3 equals 4

• x divided by 4 plus 2 equals 3

• x divided by 2 plus 4 equals 3
