Question

Como resolver 3w+2w-w=27-5w

Answer 1

3w+2w-w = 27-5w

5w - w =  27 - 5w

4w + 5w = 27

9w = 27

$x =\frac{27}{9}$

x = 3

Answer 2

- Tarea:

Resolver:

3w + 2w - w = 27 - 5w

- Solución:

✬ Resolvemos la ecuación:

3w + 2w - w = 27 - 5w

4w = 27 - 5w

4w + 5w = 27

9w = 27

w = 27 : 9

w = 3

✬ Comprobamos la ecuación:

3w + 2w - w = 27 - 5w

3 . 3 + 2 . 3 - 3 = 27 - 5 . 3

9 + 6 - 3 = 27 - 15

15 - 3 = 12

12 = 12
