Lowest common multiple of 2 and 3 is 6. So, we multiply both sides by 6. Here is the complete solution to this problem. Creative mathematicians now, as in the past, are inspired by the art of mathematics rather than by any prospect of ultimate usefulness. The essence of mathematics is not to make simple things complicated, but to make complicated things simple. I designed this web site and wrote all the lessons, formulas and calculators.

Simplifying Adding and Subtracting Multiplying and Dividing. Simplifying Multiplying and Dividing Adding and Subtracting. Introduction Exponential Equations Logarithmic Functions.

Arithmetic Progressions Geometric Progressions. I will use our second equation. Keep in mind that it is your choice which variable you want to eliminate first. The following two equations are graphed on the same xy-plane: Here's a geometric view: Here is a sample of two equations with two unknown variables: Here's what these two equations look like on the xy-plane: Eliminate x and solve for y or vice-versa. Let's go back to our original equations.

We now have this: By now you should see that our answer for x will be ZERO. Do you see what I see?

Therefore, 6 +y = 5, and y = If y = , y equals -1 in the second equation. The variable y also equals -1 in the first equation, as equals 5. Solving Systems by Elimination. When solving systems of equations by elimination, both equations in the system are added. Equations are balanced so that one variable is eliminated.
