In this tutorial, you'll see how to solve a system of linear equations by substituting one equation into the other and solving for the variable.

In this word problem, you'll need to find the solution to a system of linear equations solve the riddle and find a location on a map. There are many different ways to solve a system of linear equations.

Let's try θ = 30°: sin(−30°) = −0.5 and −sin(30°) = −0.5 So it is true for θ = 30° Let's try θ = 90°: sin(−90°) = −1 and −sin(90°) = −1 So it is also true for θ = 90° Is it true for all values of θ?

$$3x y=9$$ $$3x \left ( \right )=9$$ $$5x 4=9$$ $$5x=5$$ $$x=1$$ This value of x can then be used to find y by substituting 1 with x e.g.

In this tutorial, you'll see how to solve a system of linear equations by combining the equations together in order to eliminate one of the variables.

Then, see how find the value of that variable and use it to find the value of the other variable. Word problems are a great way to see math in action!

Consecutive Integer Problems deal with consecutive numbers.

The number sequences may be Even or Odd, or some other simple number sequences.

This tutorial introduces you to the graphing method, substitution method, and elimination method for solving a system of equations. Sometimes word problems describe a system of equations, two equations each with two unknowns.

Solving word problems like this one aren't so bad if you know what to do. Trying to solve two equations each with the same two unknown variables?
