Systems of Linear Equations
Across
1. This method is used to solve systems of equations especially when a variable is
isolated by itself in one of the equations.
4. A system of linear equations that has no solution is called this.
5. This method is used to solve systems of linear equations using addition.
8. This method of solving systems of equations involves human errors and therefore it
