Math Problem Statement

16=-2/7x

Solution

To solve the equation 16=27x16 = \frac{-2}{7}x, we need to isolate xx.

Step-by-step solution:

  1. Start with the given equation: 16=27x16 = \frac{-2}{7}x

  2. Multiply both sides of the equation by 72\frac{7}{-2} (the reciprocal of 27\frac{-2}{7}) to eliminate the fraction: x=16×72x = 16 \times \frac{7}{-2}

  3. Simplify the multiplication: x=16×72=1122=56x = \frac{16 \times 7}{-2} = \frac{112}{-2} = -56

So, the solution is x=56x = -56.
