Question

ecuaciones 144-4x=96 5w-105=45

Answer 1

144-4x=96
144 - 96 = 4x
48 = 4x
X = 48/4
X = 12

5w-105=45
5w = 45 + 105
W = 150/5
W = 30

Answer 2

Hola!

144 - 4x = 96
- 4x = 96 - 144
- 4x = - 48
x = - 48/-4
x = 12

⭐ - × - = + , por eso la división entre - 48/-4 = 12 <---- Salio positivo.

5w - 105 = 45
5w = 45 + 105
5w = 150
w = 150/5
w = 30
