-2
y - 2x < 2
-2 - 2x is greater than or equal to 6 only if x is less than or equal to -4.
There is no solution to: 4(2x + 2) + 12 > 1004(2x + 2) + 12 > 100 For 4(2x + 2) + 12 > 1004(2x + 2) + 12 to have a solution x < -1 which makes 1004(2x + 2) + 12 < 12, BUT 1004(2x + 2) + 12 is supposed to be greater than 100. Perhaps there is a missing operator in the digits of 1004?
Yes, since the expression contains more than one variable, then 2x+5y+2 is a polynomial.
2x - 2
It cannot be solved because the discriminant of the quadratic equation is less than zero
What you want to do is get x by it self so to do that you must do two things: First you must minus 4 from both sides -- so now you have -2x greater than 8. Second you must divide by -2 however if you multiply or divide by a negative number in a greater than or less than equation then you must flip the sign -- thus you end up with x is LESS THAN -4. -2x + 4 > 12-2x + 4 - 4 > 12 - 4-2x > 8-2x/-2 < 8/-2x < -4
-2 is less than plus 3.
