Ibeg you i really need ! 25 points

[2x-3]+5=14
[2x-3]=14-5
[2x-3]=9

1)                         2)
2x-3=9                 2x-3=-9
2x=12                  2x=-6
x=12/2=6             x=-6/2=-3

x=-3,6

2x+4x=15
6x=15
x=15/6=5/2=2+1/2=2  1/2

x=2 1/2

4x+6=-x-19
4x+x=-19-6
5x=-25
x=-25/5=-5

x=-5

3/4 +1/2 x=7/2
L.C.M=4
3+2x=14
2x=14-3
2x=11
x=11/2

x=11/2

In the equation 5(2x+4)-7x=9 the first sep that   should be done to solve for x is
Distribute 5 to both terms inside the parenthesis.
5(2x+4)-7x=9
10x+20-7x=9
3x=-11
x=-11/3

Identifiy the independet variable in the stament.
can be speed:
f(v)=50/v

But, I need more information in this question. 

Question 42
f(4)=9

Question 43
f(-3)=3*(-3)+2=-9+2=-7
