Solving Equations in 8th Grade Math

The video tutorial guides students through solving equations with two examples. It starts with an introduction to the assignment and a code for the day. The first example involves solving the equation 2T + 1 = 9 by subtracting and dividing to find T. The second example demonstrates solving 2(C + 6) = 14 by dividing and subtracting to find C. The tutorial concludes with encouragement for students to practice and ask questions.
