Algebraic Equations: Solve for Variable with Multiple Variables
In Part 4 of our lesson series on Algebra, this lesson focuses on solving for variables in equations containing multiple variables. The key to solving for variables in algebraic equations with multiple variables is to remember that our answer will still have a variable in it.
Example: Solve for x in the equation
Note, in this example there are two variables. Our answer will still have a variable in it as we will solve for x in terms of y. Let’s go through the example to illustrate this!
Step 1: Isolate the x, start with addition or subtraction.
To remove the +1 we have to -1 from both sides
Step 2: Isolate the x, by taking care of the multiplication and division next.
Remove the 2 by multiplying both sides by 2 and simplify by expanding the equation!
