Answer 1

Respuesta:

1. -6

2. 5

3. 0.25

4. -6

5. 4.75

6. 3

Explicación paso a paso:

1.

2x + 15 = 3

2x = 3 - 15

2x = -12

x = -12/2

x = -6

2.

3x - 7 = 8

3x = 8 + 7

3x = 15

x = 15/3

x = 5

3.

4b + 5 = 6

4b = 6 - 5

4b = 1

b = 1/4

b= 0.25

4.

3x + 6 = -12

3x = -12 - 6

3x = -18

x = -18/3

x = -6

5.

-26 + 4n = -45

4n = -45 + 26

4n = -19

n = -19/4

n = 4.75

6.

18 - 5x = 16

-5x = 16 - 18

-5x = -2

x = -2 + 5

x = 3
