linear equation?

1.
3x/2 - 4 = 5
add 4 to both sides of the equation
3x/2 = 4 + 5
3x/2 = 9
multiply both sides of the equation by 2
3x = 18
divide both sides by 3
x = 6

b.
1.
2w - 7/4 = 0
add both sides by 7/4
2w = 7/4
multiply both sides by ½
w = 7/8

2.
18 - 2m/5 = -2
subtract both sides by 18
-2m/5 = -20
multiply both sides by 5
-2m = -100
divide both sides by -2
m = 50

6p - (11/-4) = 5
6p = 11/-4 + 5
6p = -11/4 + 20/4
6p = 9/4
p = 9/(4*6)
p = 3/8

a1 x=6

1. 2w-7/4=0 multiply by 4 to eliminate the fractions
8w-7=0
w=7/8
2. 18-2m/5=-2 multiply by 5 to eliminate the fraction
90-2m =-10
-2m= -100
m=50
3. 6p-11/-4=5 multiply by -4
6p-11=-20
6p= -9
p=-3/2

3x/2 -- 4 = 5 => 3x/2 = 9 => x = 9*2/3 = 6

2w -- 7/4 = 0 => 2w = 7/4 => w = 7/4*2 = 7/8

18 -- 2m/5 = --2 => 2m/5 = 20 => m = 20*5/2 = 50

6p -- 11/(-4) = 5 => 6p = 5 -- 11/4 = 9/4 => p = 9/4*6 = 3/8

1)
3x/2 - 4 = 5
3x/2 = 5 + 4
3x/2 = 9
3x = 2(9)
3x = 18
x = 18/3
x = 6

2)
(2w - 7)/4 = 0
2w - 7 = 4(0)
2w - 7 = 0
2w = 7
w = 7/2 (3.5)

3)
18 - 2m/5 = -2
-2m/5 = -2 - 18
-2m/5 = -20
-2m = 5(-20)
-2m = -100
m = -100/-2
m = 100/2
m = 50

4)
(6p - 11)/-4 = 5
6p - 11 = -4(5)
6p - 11 = -20
6p = -20 + 11
6p = -9
p = -9/6
p = -3/2 (-1.5)

3x/2 = 9
3x = 18
x = 6

2w = 7/4
w = 7/8

- 2m/5 = - 20
2m/5 = 20
2m = 100
m = 50

6p + 11/4 = 5
6p = 9/4
p = 9/24
p = 3/8
Or perhaps , for final question , you mean :-
(6p - 11) / (- 4) = 5
6p - 11 = - 20
6p = - 9
p = - 9/6
p = - 3/2

3x/2 - 4 = 5
3x/2 = 9
3x = 18
x = 6

2w-7/4=0
2w = 7/4
w = 7/8

18-2m/5=-2
-2m/5 = -20
m = 50


Are you missing some parentheses? One usually does not usually see double negatives. In any case, I'm going to assume you meant this...

(6p-11)/-4=5
6p-11 = -20
6p = -9
p = - 1 1/2

a) 3x / 2 -4 =5
3x/2 = 5+4
3x = 9 x 2
x = 18/3
= 6

b)1. 2w - 7/4 = 0
2w = 0 + 7/4
w = 1.75/2
= 0.875

2. 18 - 2m/5 = -2
-2m/5 = -2 - 18
2m/5 = 20
2m = 20x5
m = 100 / 2
= 50

3. 6p-11/-4 = 5
6p = 5 - 11/4
6p = -2.25
p = -2.25/6
= - 0.375

3x/2-4=5
x=6
