Id say you would do it the same as you do to , multiply them all out so you can take it away etc juct having to find out one other number.

Simultaneous equations are where you have multiple equations, often coupled with multiple variables. An example would be x+y=2, x-y=2. To solve for x and y, both equations would have to be used simultaneously.

Can't be done unless you have another equation with the same x and y. Then you would solve for simultaneous equations.

They are simultaneous equations

Then they are simultaneous equations.

You can solve the system of equations with three variables using the substitute method, or using matrix operations.
