How do you solve the simultaneous equations #3x-4y=11# and #5x+6y=12#?
You can solve this system of equations by using the multiplication method.
The first thing that you need to do is pick a variable to eliminate first, then figure out the least common multiple (LCM) of its coefficients.
Let's say that you want to eliminate
So, multiply the first equation by
Add the left side and the right side of these two equations separately to get
Now use this value of
The solutions to this system of equations are
