Solving Equations: A Comprehensive Review

The video tutorial reviews solving equations from seventh grade, starting with simple two-step equations and progressing to more complex ones involving distribution, combining like terms, and variables on both sides. The teacher provides step-by-step instructions and examples, emphasizing key concepts such as handling negative coefficients and ensuring balance in equations. The video concludes with homework instructions and encourages students to try their best.

What is the first step in solving a two-step equation?

• Add or subtract to isolate the variable

• Combine like terms

• Divide both sides by the same number

• Multiply both sides by the same number
