2x + 3 > 72x + 3 - 3 > 7 - 32x > 42x/2 > 4/2x > 2The solution is all real numbers greater than 2.
x < -26.
2x + 4 is an expression, not an equation. There can be no solution set for an expression.
2x2 + 2x - 8 = 2(x2 + x - 4). This can take any value greater than or equal to -8.5
2x-6 < 5+7x 2x-7x < 5+6 -5x < 11 x > -2.5
2x + 3 > 72x + 3 - 3 > 7 - 32x > 42x/2 > 4/2x > 2The solution is all real numbers greater than 2.
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?
5 + 2x ≥ 13 Subtract 5 from both sides: 2x ≥ 8 Divide both sides by 2: x ≥ 4
x < 3
x < -26.
It has no solution because the discriminant of the quadratic expression is less than zero.
2x plus 3y
The solution to the equation 2x plus 2 is 2(x + 1).
2x + 4 is an expression, not an equation. There can be no solution set for an expression.
2x + 2 > x + 5
2x - 12 > 2 + x x - 12 > 2 x > 14
2x2 + 2x - 8 = 2(x2 + x - 4). This can take any value greater than or equal to -8.5
