In this worksheet, you'll practise solving systems of linear equations using the elimination method, one of the key techniques for solving simultaneous equations.
The elimination method involves combining two equations in a system in a way that eliminates one of the variables, usually by adding or subtracting the equations. This allows you to solve for the remaining variable and then substitute it back to find the other.
A Review of the Elimination Method in Algebra
Suppose you have the following system of equations:
You can eliminate the ( x ) variable by subtracting Equation 2 from Equation 1:
Now substitute ( y = 3 ) back into one of the original equations:
So, the solution is ( x = 3.5 ), ( y = 3 ).
