Q. Solve for all values of x in simplest form.9=∣−3+3x∣Answer: x=
Understand absolute value equation: Understand the absolute value equation.The equation 9=∣−3+3x∣ involves an absolute value, which means the expression inside the absolute value, −3+3x, can be either positive or negative, but the result after applying the absolute value will be non-negative. We need to consider both cases where −3+3x is positive and where it is negative.
Set up two equations: Set up two separate equations to solve for x. Since the absolute value of a number is always non-negative, we can have two cases: Case 1: −3+3x is positive or zero, so we can drop the absolute value bars. Case 2: −3+3x is negative, so we take the opposite of the expression inside the absolute value. This gives us two equations to solve: 1. −3+3x=92. −3+3x=−9
Solve first equation: Solve the first equation −3+3x=9. Add 3 to both sides of the equation to isolate the term with x on one side: −3+3+3x=9+33x=12 Now, divide both sides by 3 to solve for x: 33x=312x=4
Solve second equation: Solve the second equation −3+3x=−9. Add 3 to both sides of the equation to isolate the term with x on one side: −3+3+3x=−9+33x=−6 Now, divide both sides by 3 to solve for x: 33x=3−6x=−2
Combine solutions: Combine the solutions from both cases.We have found two solutions for x from the two cases:From Case 1: x=4From Case 2: x=−2These are the two values of x that satisfy the original equation.
