Math Problem Statement

|3x-5|=3

Solution

To solve the equation 3x5=3|3x - 5| = 3, we must consider the definition of absolute value. An absolute value equation A=B|A| = B has two possible solutions:

  1. A=BA = B
  2. A=BA = -B

In this case, A=3x5A = 3x - 5 and B=3B = 3. So, the two cases are:

Case 1:

3x5=33x - 5 = 3 Solving for xx: 3x=3+53x = 3 + 5 3x=83x = 8 x=83x = \frac{8}{3}

Case 2:

3x5=33x - 5 = -3 Solving for xx: 3x=3+53x = -3 + 5 3x=23x = 2 x=23x = \frac{2}{3}

Thus, the two solutions are: x=83orx=23x = \frac{8}{3} \quad \text{or} \quad x = \frac{2}{3}
