Solving Systems of Equations using Elimination

2. Use when both the equations are in Standard Form
Find a term from each equation with the same variable with the same coefficient.
If no same coefficients, then multiply one of the terms in either or both equations to get a common term (similar to finding common denominators with adding and subtracting fractions) that we can eliminate.
If the terms have the same sign we subtract one equation from the other. If the terms have different signs we add one equation to another.
Once we have added or subtracted, we now have one variable that we can solve for.
After solving for one variable, plug it into the original equation to solve for the other.
