Question

Ayudenme a resolverlo , ecuación de 1er grado .. GRACIAS!!

Answer 1

Ahí te va la solución...

Answer 2

2x/14 = 3

2x = 3 (14)

2x  =42

x = 42/2

x = 21
-----------------------------------

(x - 1)/2 = 1

x - 1 = 1 (2)

x - 1 = 2

x = 2 + 1

x = 3
----------------------------------------

(2x + 3)/4 = 1

2x + 3 = 1 (4)

2x + 3 = 4

2x = 4 - 3

2x = 1

x = 1/2
------------------------------------------

(5x - 1)/2 = 3

5x - 1 = 2 (3)

5x - 1 = 6

5x = 6 + 1

5x = 7

x = 7/5
----------------------------------------

(3x + 2)/4 = 1

3x + 2 = 1 (4)

3x + 2 = 4

3x = 4 - 2

3x = 2

x = 2/3
