Solving Linear Equations and Variables

The video tutorial explains how to solve linear equations by isolating the variable. It covers four examples: solving for m in 6m = -30, for z in 8 = -2z, for w in w/6 = 5, and for x in -2 = x/-4. Each example includes a step-by-step solution and verification process to ensure the solution is correct.

What is the first step in solving an equation?

• Add a constant to both sides

• Isolate the variable

• Multiply both sides by zero

• Subtract the variable from both sides
