Answer:

x = 70

Step-by-step explanation:

Step 1: Simplify both sides of the equations.

  • \frac{x}{10} = \frac{5x}{7}-43
  • \frac{1}{10}x=\frac{5}{7}x-43

Step 2: Subtract 5/7x from both sides.

  • \frac{1}{10}x- \frac{5}{7}x = \frac{5}{7}x - 43 - \frac{5}{7}x
  • \frac{-43}{70}x = -43

Step 3: Multiply both sides by 70/(-43).

  • \frac{-43}{70}x * \frac{70}{-43} = -43*\frac{70}{-43}
  • x = 70

Step 4: Check if solution is correct.

  • \frac{(70)}{10}=\frac{5(70)}{7}  -43
  • 7 = \frac{350}{7} - 43
  • 7 = 50 - 43
  • 7 = 7

Therefore, x = 70.
