In this lesson we’ll look at how to solve a multivariable equation for a certain variable in terms of the others. When you solve an equation for a variable you’re moving the other terms and coefficients around by using inverse operations to isolate the variable you’re solving for.
Read MoreInverse operations are operations that are opposite or “undo” each other. For example, addition undoes subtraction and division undoes multiplication. Inverse operations are useful when solving equations.
Read MoreWhen you need to solve equations with variables on both sides of the equals sign, make sure to move all the variables to one side of the equation together. A simple saying that may help you remember this is “get all your x’s to Texas.” In other words, you need to move all the x terms so that they’re on the same side of the equation.

Read MoreTwo-step problems are problems in which you need to not only solve an equation for the value of a variable, but then also use the solution to evaluate some other expression that depends on that same variable.
Read MoreWe’ll solve for the variable in a radical equation by isolating the radical, squaring both sides and then using inverse operations.
