Answer:
1: x = 19 y = 16 ; 2. x = 5 y = -4
Step-by-step explanation:
To check your work plug the numbers back into one of the equations and see if it's true.
For example:
10(19)-9(16)=46
46=46
1. I distributed 3 to all the numbers so that 9y and -9y would cancel then you add like terms.
2. I distributed -4 to all the numbers so that 4x and -4x would cancel. Then add all like terms.
Once you get x or y plug it back into one problem to get the other variable.
Hope this helps!
