Math Problem Statement

x/8=-2/11

Solution

To solve the equation:

x8=211\frac{x}{8} = \frac{-2}{11}

We can cross-multiply to eliminate the denominators:

x11=28x \cdot 11 = -2 \cdot 8

Simplifying both sides:

11x=1611x = -16

Now, solve for xx by dividing both sides by 11:

x=1611x = \frac{-16}{11}

So, the solution is:

x=1611x = \frac{-16}{11}
