Can someone help me on the following?. 14.5n – 4 = 8 15. 2x + 5 – 4x = -3 16. 96=-6(-4 -3y)


17. 3(x – 5) = -14 + 7x 18. 7z + 10 – z = 8z – 2(z – 5)

14. 5n - 4 = 8
           5n = 12
             n = 2.4

15. 3x + 5 - 4x = -3
              -x + 5 = -3
                    -x = -8
                     x = 8

16. 96 = -6(-4 - 3y)
      96 = 24 + 18y
      72 = 18y
        4 = y

17. 3(x - 5) = -14 + 17x
      3x - 15 = -14 + 17x
   -11x - 15 = -14
          -11x = 1
               x = -0.0909

18. 7z + 10 - z = 8z - 2(z - 5)
           6z + 10 = 8z - 2z + 10
           6z + 10 = 6z + 10
                   6z = 6z
                     z = z   (all real numbers are solutions)

Hope this helps.
