Answer:
Explanation:
Example:
If you have the inequality 3<(x/9)+7
Begin with subtraction by subtracting 7 from both sides, rather than beginning with the parentheses x/9.
Do all processes to both sides of the inequality until you have solved for x.
Example: As mentioned in the previous step, you would begin by subtracting 7 from both sides.
So 3<(x/9)+7 becomes, -4<x/9
Now you would multiply both sides by 9 because the fraction x/9 is the same as x divided by 9, and the opposite of division is of course multiplication.
This process leaves you with the solution, -36<x, so x is greater than -36.
Remember that if your problem requires you to multiply or divide by a negative number, then you need to flip the inequality sign when you do so.
For example: If instead of multiplying by 9 in the previous problem you had to multiply by -9, you would get 36>x rather than 36<x.
