Understanding and Solving Equations with Decimals

The video tutorial explains how to solve an equation with decimals by simplifying both sides, clearing decimals, and isolating the variable. It demonstrates the process of combining like terms, multiplying to remove decimals, and using division to solve for the variable. The solution is verified by substituting it back into the original equation.

What is the first step in solving an equation with decimals?

• Add a constant to both sides

• Multiply by a power of 10

• Subtract a constant from both sides
