Question

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)


19. Solve the equation = 2 + 2 for the variable .

Answer 1

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.
