Answer 2

To solve the equation |x| + 4|x| = 9, we need to consider two cases: when x is positive and when x is negative.

Case 1: x is positive In this case, |x| is equal to x. Therefore, the equation becomes x + 4x = 9, which simplifies to 5x = 9. Solving for x, we get x = 9/5.

Case 2: x is negative In this case, |x| is equal to -x. Therefore, the equation becomes -x + 4(-x) = 9, which simplifies to -5x = 9. Solving for x, we get x = -9/5.

So, the solutions to the equation |x| + 4|x| = 9 are x = 9/5 and x = -9/5.

Please note that these solutions have been derived based on the given equation.
