Question

1. 5a − 1 = 14

2. 5x − 9 = 3(x − 2)

3. 4x − 8 = −4(2x − 3) + 4

4. n + 8 = 10

Answer 1

Respuesta:

1. a = 3

2. x = 3/2

3. x = 2

4. n = 2

Explicación paso a paso:

1. 5a - 1 = 14

5a = 15

a = 3

2. 5x - 9 = 3(x - 2)

5x - 9 = 3x - 6

5x - 3x = 9 - 6

2x = 3

x = 3/2

3. 4x - 8 = -4(2x - 3) + 4

4x - 8 = -8x + 12 + 4

8x + 4x = 16 + 8

12x = 24

x = 2

4. n +8 = 10

n = 2
