Solving linear equations using linear combinations basically means adding several equations together so that you can cancel out one variable at a time.
For example, take the following two equations: x+y=5 and x-y=1
If you add them together you get 2x=6 or x=3
Now, put that value of x into the first original equation, 3+y=5 or y=2
Therefore your solution is (3, 2)
But problems are not always so simple.
For example, take the following two equations: 3x+2y=13 and 4x-7y=-2 to make the "y" in these equations cancel out, you must multiply the whole equation by a certain number.

How can you solve real-world mathematical problems using two linear equations in two variables?
To solve real-world mathematical problems using two linear equations in two variables, you can first identify the variables that represent the quantities of interest. Next, formulate two equations based on the relationships and constraints given in the problem. By using methods such as substitution or elimination, you can solve the equations simultaneously to find the values of the variables. This approach allows you to determine solutions that address the specific scenario being analyzed, such as budgeting, mixing solutions, or determining rates.
