Answer:

  • x = 1.25
  • y = 1.75

Explanation:

Find x

  • 8/10 = 5/(5 + x) Cross multiply
  • 8*(5 + x) = 10*5 Combine on the right
  • 8(5 + x) = 50 Remove the brackets on the left.
  • 40 + 8x = 50 Subtract 40 from both sides.
  • 40-40 +8x = 50-40 Combine
  • 8x = 10 Divide by 8
  • 8x/8 = 10/8 Divide
  • x = 1.25

Find y

  • 7/(7 + y) = 8/10 Cross multiply
  • 8*(7 + y) = 10 * 7 Combine the right
  • 8(7 + y) = 70 Remove the brackets.
  • 56 + 8y = 70 Subtract 56 from both sides
  • 56 - 56 + 8y = 70 - 56 Combine
  • 8y = 14 Divide by 8
  • y = 1.75
