QUESTION:
solve the inequality.
5(4-z)+5z-6>3z-8+1

ANSWER:

5(4-z)+5z-6>3z-8+1

Remove the parenthesis,

5*4- 5*z + 5z - 6 > 3z -8 + 1

20- 5z + 5z - 6 > 3z -8 + 1

20- 6 > 3z -8 + 1

14 > 3z - 7

Add 7 to both sides of the equation,

==> 14 + 7 > 3z - 7 + 7

==> 21 > 3z

Divide both sides by 3 ( because here 3 is multiplied by z)

==> 21/3 > 3z/3

==> 7 > z

So the value of z is less than 7

Hope you understood.
