In this lesson, the instructor covers how to solve linear equations that involve grouping symbols like parentheses or brackets. The first step is to simplify the left-hand side using the distributive property, then simplify the equation by adding like terms. After that, use the addition or multiplication property to isolate the variable on one side of the equation. Finally, check the solution by plugging it into the original equation and simplifying both sides. The lesson also presents an alternate way to solve the equation using fractions or dividing both sides by a coefficient.
