What are the answers for number 10,11,12

10. 2 consecutive integersx = smaller one, x + 1 = larger one
      2(x + 1) = 3x - 15
      2x + 2 = 3x - 15
      2 + 15 = 3x - 2x
      17 = x

x + 1 = 17 + 1 = 18
so ur 2 numbers are : 17 and 18

11. 2 consecutive odd integersx = smaller one and x + 2 = larger one
      5(x + 2) = 8x + 1
      5x + 10 = 8x + 1
      10 - 1 = 8x - 5x
       9 = 3x
       9/3 = x
       3 = x

x + 2 = 3 + 2= 5
so ur 2 numbers are : 3 and 5

12. 2 consecutive even integersx = smaller onex + 2 = larger one
      1/2x = x + 2 + 2
      1/2x = x + 4
      1/2x - x = 4
      1/2x - 2/2x = 4
      -1/2x = 4
        x = 4 * -2
        x = -8

x + 2 = -8 + 2 = -6
so ur 2 numbers are : -6 and -8
