That means the number of hours is our variable. And there is nothing like a set of co-ordinate axes to solve systems of linear equations.
Then by either factoring or using the quadratic formula, you will find the solution to x. Usually coin problems involve two equations: Algebra is much more interesting when things are more real.
This means, divide both sides of the equation by r, the rate. Algebra - Solving Word Problems with Two Variables 1 of 5 Provides explanation of how to solve word problems using two variables.
This will involve further steps: If you are not confident in your abilities to solve two-step equations with word problems, you can go to one-step equations — word problems and practice some more before continuing with this lesson. Without much ado, here are effective tips that can help you conquer this rather difficult subject.
How many coins of each type does she have?
We want to find Karen's age, so let's call that K. Go through your operations one more time and see if you have done everything correctly.
