Q. Solve for all values of y in simplest form.12=∣∣9y∣∣Answer: y=
Understand absolute value equation: Understand the absolute value equation.The absolute value of a number is its distance from zero on the number line, regardless of direction. Therefore, the equation ∣9y∣=12 can have two possible solutions: one where 9y is positive and equals 12, and one where 9y is negative and equals −12.
Solve for y when positive: Solve for y when 9y is positive.If 9y=12, then multiplying both sides by 9 gives us y=12×9.
Calculate positive value of y: Calculate the positive value of y.y=12×9y=108
Solve for y when negative: Solve for y when y/9 is negative.If y/9=−12, then multiplying both sides by 9 gives us y=−12×9.
Calculate negative value of y: Calculate the negative value of y.y=−12×9y=−108
