Given the numerical inequality
3x + 5 ≥ 7
Determine the solution.
Solution:
In order to find for the solution, we simply need to solve for x. The first step is to transpose 5 to the other side of the equation, hence it must be taken to note that in transposing a number the sign changes.
3x + 5 ≥ 7
3x ≥ 7 - 5
3x ≥ 2
Divide both sides by 3, in order to cancel out 3x, leaving behind x.
3x/3 ≥ ⅔
x ≥ ⅔
Final answer:
x ≥ ⅔
