We isolate the variable by removing other terms on the same side. For example, if a + 5 = 54, we subtract 5 from both sides to find a = 49. Finally, we check our solution by substituting the value back into the original equation.

We focus on understanding the meaning of equations, like 7x = 14, and using techniques like dividing both sides of the equation by the coefficient to isolate the variable. This method helps us find the value of the unknown variable, making algebra easier and more approachable.

In this video we dive into the concept of moving constant values from one side to other, while changing its sign. Which is also called transposing of a number.

It takes two steps because he first has to subtract 2 from both sides and then multiply both sides by 4. Courses on Khan Academy are always 100% free. Start practicing—and saving your progress—now!
