1. Problem Description

We are given the equation 3x2=x17\frac{3x}{2} = \frac{x-1}{7} and need to solve for xx.

2. Solution Steps

To solve the equation 3x2=x17\frac{3x}{2} = \frac{x-1}{7}, we can start by cross-multiplying.
7(3x)=2(x1)7(3x) = 2(x-1)
Simplify both sides of the equation:
21x=2x221x = 2x - 2
Subtract 2x2x from both sides of the equation:
21x2x=2x22x21x - 2x = 2x - 2 - 2x
19x=219x = -2
Divide both sides by 19 to isolate xx:
x=219x = \frac{-2}{19}

3. Final Answer

x=219x = -\frac{2}{19}
