Question

4-3-2x/5=7 ayudenme con esta ecuación

Answer 1

Resolver.

4 - 3 - 2x/5 = 7
1 - 2x/5 = 7
1 - 7 = 2x/5
- 6 = 2x/5
- 6 * 5 = 2x
- 30 = 2x
- 30/2 = x
- 15 = x

Respuesta.
x = - 15

Answer 2

4 - 3 - 2x/5 = 7

1 - 2x/5 = 7

(1 * 5 - 2x)/5 = 7

5 - 2x = 7 (5)

5 - 2x = 35

- 2x = 35 - 5

- 2x = 30

x = 30/-2

x = - 15

Solución : 

x = - 15
