What is systems of equations?
A set of 2 numbers that represent the X and Y coordinate, these coordinates resemble the intersection point.
How do you solve a system of equation?
There are 3 ways to solve a system of equations: graphing, substitution, elimination.
Graphing
Draw the lines from the equation with their approximate slope. The intersection point represents the system of equations.
Substitution
To start you must isolate one of the variables in the equation, and then replace the same variable( on the other side of the equation) with the numbers/variables it is equal to. Lastly, you must use distributive property.
Elimination
First, find the least common multiple of the X values, so that your X values cancel each other out. Lastly, you would add them together and solve.
