4x + 7 is an expression, not an equation. Only an equation (or an inequality) can have solutions, an expression cannot have a solution.
Through signs of inequality Solve each inequality Graph the solution? 2(m-3)+7<21 4(n-2)-6>18 9(x+2)>9(-3)
If: 6x-4+7 = 5 Then: x = 1/3
If 7 > 3x - 2 then x < 3.

Do you mean 3 + 4|3x + 7| ≤ - 89? There is no solution to the inequality, since it is a false statement. A positive number cannot be equal or less than a negative number. On the left side, you are dealing only with positive numbers, since the absolute value is always positive, no matter what the values of x are.
n + 21 ≥ 7 Subtract 21 from both sides: n ≥ -14
The inequality with the terms 2x, 3 and 7 can be written as 2x -3 = 7, 2x + 3 = 7, 2x * 3 = 7, and 2x/3 = 7. This means that the solutions are 5, 2, 7/4, and 21/2 respectively.
