In this video, I will go over 3 linear system of equations math problem, in order of difficulty. The first step is to select the variable you want to eliminate. Your goal is to manipulate 1 or both equations so that one variable has the same coefficients in both equations, but with opposite signs."

Then add the 2 equations together. This will eliminate the variable with the same, but opposite signs, coefficient. The result is an equation with one variable.

Solve for the one variable. Take the value you found for the one variable and substitute it into one of the original equations to find the value of the other variable.

Write the solution as an ordered pair: (x, y).
