Answer:
y = 0
x = 8
Step-by-step explanation:
subtract second equation from first one
3x - 6y - (3x - y) = 24 - 24 the - sign in front of the parenthesis effects the inside expressions
3x - 6y - 3x + y = 24 - 24 add/subtract like terms
-5y = 0 and so y = 0
to find the value of x we can use this information
3x - y = 24 since y = 0
3x = 24 divide both sides by 3
x = 8
