solution

4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.

6

If (x+7) > 10, then x > 3. If (x+7) < 10, then x < 3.

-2

14 49 2401

-7

2 < 2x + 4 < 18 Subtract 4: -2 < 2x < 14 Divide by 2: -1 < x < 7

2x + 3 > 72x + 3 - 3 > 7 - 32x > 42x/2 > 4/2x > 2The solution is all real numbers greater than 2.
