This is the updated versionThis video shows students how to solve 2-step Algebra equations involving on. 3x - 4 11. The sum of the two numbers is 15.

Lets say equation 1 is 2x 4y 5 and equation 2 is 3x - 2y 10. Let x stand for the larger number and y stand for the second number. However the problems are expressed in terms of a stated variable and the student is asked to write an equation using that variable before solving the problem.

Now we will add equation 1 and equation 3 which is 2x 4y 6x - 4y 5 20 simplify and we get 8x 25. Now solve by adding the two equations. You may have recognized the equation C 2πr.

Now that we know the value of x we can replace it in the equation with 5. Program to solve factor for. Math 6th grade Variables expressions Evaluating expressions word problems Evaluating expressions with variables word problems CCSSMath.
