- The text explains how to solve systems of linear equations using the substitution and combination methods
- For substitution, isolate a variable in one equation and substitute the result into the other equation
- For combination, make sure the coefficients of one variable have the same absolute value and then add or subtract the equations to eliminate one variable
- The number of possible solutions in a system of linear equations is determined by whether the lines intersect at one point, have the same x and y values, or are parallel with the same slope
- If the system of equations has different slopes, it has no solution, while the same slope and y-intercept indicate infinitely many solutions
