1. (15m + 3)/2 = -6?

1. (15m + 3)/2 = -6
15 m + 3 = -12
15 m = -15
m = -1

2. (3/2) x - 15 = -12
(3/2) x = 3
3x = 6
x = 2

3. -7x + 3 = -15/2
-7x = -21/2
7x = 21/2
14x = 21
x = 3/2

4. 4x + (1/2)(12 x + 2) = 3
4x + 6x + 1 = 3
10 x + 1 = 3
10 x= 2
x = 5

5. (3/2)(x+8) = 6x
x + 8 = 4x (dividing by 3/2 = multiplying by 2/3)
3x = 8
x = 8/3

Question 1
15m + 3 = - 12
15m = - 15
m = - 1

Question 2
3x - 30 = - 24
3x = 6
x = 2

Question 3
- 7x = - 3 - 15/2
- 7x = - 6/2 - 15/2
-7x = - 21/2
7x = 21/2
x = 3/2

Question 4
4x + 6x + 1 = 3
10x = 2
x = 2/10
x = 1/5

Question 5
3x + 24 = 12x
9x = 24
x = 24/9
x = 8/3

1)
(15m + 3)/2 = -6
15m + 3 = -12
15m = -12 - 3
15m = -15
m = -15/15
m = -1

2)
(3/2)x - 15 = -12
3x/2 = -12 + 15
3x/2 = 3
3x = 6
x = 6/3
x = 2

3)
-7x + 3 = -15/2
-14x + 6 = -15
-14x = -15 - 6
-14x = -21
x = -21/-14
x = 3/2
x = 1 1/2

4)
4x + (1/2)(12x + 2) = 3
4x + (12x + 2)/2 = 3
8x + 12x + 2 = 6
20x = 6 - 2
x = 4/20
x = 1/5

5)
(3/2)(x + 8) = 6x
(3x + 24)/2 = 6x
3x + 24 = 12x
12x - 3x = 24
9x = 24
x = 24/9
x = 8/3
