How to solve absolute value inequalities with x on both sides?
In order to solve the absolute value inequality with x on both sides you will need to use the properties of absolute values. The following properties can be used when solving absolute value inequalities with x on both sides:
How to solve absolute value inequalities with x cubed on
Squaring an absolute value inequality with x cubed on both sides will not make the inequality easier. In fact, it will often make solving it more difficult. For example, look at the absolute value inequality or equivalently These two absolute value inequalities are equivalent because is the same as However, square each of these absolute value inequalities and you get and These two absolute value inequalities are not equivalent because now the two sides are different. It is
Absolute value inequalities with x on both sides?
If you have an absolute value inequality with x on both sides, you can solve it by multiplying both sides by the opposite sign of the exponent. This gives you a fraction. Then, if the denominator is positive, you can take the square root of the resulting fraction. If the denominator is negative, you need to flip it and take the negative root.
Solve absolute value inequalities with x on both sides?
You can solve absolute value inequalities with variables on both sides by taking the absolute value of each side. For example, if you want to solve 6|x| - 7 ≤ -3, you can take the absolute value of each side to find that |6| - 7 ≤ -3. The absolute value of -3 is 3, so this inequality is equivalent to 3 ≤ 6 - 7. If the absolute value of the left side is greater than the right side, the original inequality is
Absolute value inequalities with x on the right?
If you have an absolute value inequality with an x on the right, or a number on the right, but no number on the left, you can solve this inequality by multiplying both sides by the reciprocal of the number on the right. This gives you an inequality with a smaller absolute value on the left side and that’s easier to solve. So, if you have an absolute value inequality with a variable on the right but no variable on the left, you can try multiplying both sides by the
