4 - (2x - 3) = 3
4 - 2x + 3 = 3
-2x = 3 - 3 - 4
-2x = -4
x = 2 answer
Eliminate one of the variables..
2x + 2y = 28
2x = -2y + 28
8x - 2y= 22
8x = 2y + 22
x = 0.25y + 2.75
combine equations...
-y +14 = 0.25y + 2.75
solve for the variable..
-y - 0.25y = 2.75 - 14
-1.25y = -11.25
y = 9
replace y with 9 in previous equation..
x = -y + 14
x = -9 + 14
x = 5
so y = 9 and x = 5
I hope I did that right good luck!

To classify all of these numbers, you could say all real numbers if not for the square root of -100, as it is 10i, which is an imaginary number. The only classification that applies to all of these these numbers is "All real and imaginary numbers"
