The easiest way to tell if a number is rational or not is to attempt to express it as a fraction. If you can, then the number is rational. If not, then the number is irrational. All integers are rational numbers, because they can be written as a fraction (for example, the integer 8 = 8/1). But numbers like pi or sqrt(2) cannot be written as a fraction and are not rational.
Answer:
x=-17
y=-2 2/3
Step-by-step explanation:
start with the second one and do substitution
x -6y=-1 add the -6y over to get x alone
x=6y-1 put this into first equation
2(6y-1)-15y=6 distribute
12y-2-15y=6 add like terms
-3y-2=6 add the -2 over
-3y=8 divide by -3
y=-2 2/3 put this back into the first equation that was solved for x
x=6(-2 2/3)-1 distribute
x=-17
