Verifying Solutions and Operations

The video tutorial explains how to solve equations by isolating variables on one side and moving coefficients and constants to the other. It demonstrates using reciprocal operations to solve equations, including those involving fractions. The tutorial also covers finding common denominators to simplify and solve equations effectively.

What is the first step in isolating a variable when it is divided by a number?

• Add the number to both sides

• Multiply by the reciprocal of the number

• Subtract the number from both sides

• Divide by the reciprocal of the number
