simplified:
2x + 2y = 6 . . . . . (1)
x + 3y = -1 . . . . . (2)
(1) x 3 => 6x + 6y = 18 . . . . . (3)
(2) x 2 => 2x + 6y = -2 . . . . . (4)

x = 20/4 = 5
Answer:
Rational
Step-by-step explanation:
okay so a natural number is anything like 1,2,3,4...etc.
a whole number is like a natural number but includes 0's

but keep in mind all of these are whole numbers or can be made into a whole number (not including natural numbers)
this leaves...
Rational
now here is a word of advice every mixed number and fraction is rational because its already in a solved and complete form but a decimal that could be solved like 0.77777 or 0.345 with a line over it or 64 squared
Irrational
a number that has no end and cant be solved like 0.86866968..... or 38 squared
