one approach first pick a variable to eliminate using 2 equations at a time eliminate the same variable you will now have one set of simultaneous equation with 2 variables solve use these values in the expression for the eliminated variable to find that value. always a good practice to check your solution in the original. take a minute to try this then I will work with you if you get stuck. best if you show your work. If you have any questions please ask.
