Solve the equation: (1/5)x + 6/5 = (1/7)x + 8/7

Solution

Here is the solution to your equation:

We are solving: 15x+65=17x+87\frac{1}{5}x + \frac{6}{5} = \frac{1}{7}x + \frac{8}{7}

Step 1: Eliminate the fractions by finding the least common denominator (LCD).

  • The denominators are 55 and 77, and their LCD is 3535.
  • Multiply the entire equation by 3535:

35(15x+65)=35(17x+87)35 \cdot \left(\frac{1}{5}x + \frac{6}{5}\right) = 35 \cdot \left(\frac{1}{7}x + \frac{8}{7}\right)

This simplifies to: 7x+42=5x+407x + 42 = 5x + 40

Step 2: Simplify and solve for xx.

  • Bring xx-terms to one side: 7x5x=40427x - 5x = 40 - 42 2x=22x = -2

  • Divide by 22: x=1x = -1

Final Answer:

The solution is: 1\boxed{-1}
