1. Solucionar las siguientes ecuaciones
x-3= 3 - x
21-3=6+
• 2. = 6
x + x = 2x
1 + x +2 = x + 3
• X-1 = x + 1
X-X=1
5x - x = 3x + 1​

Answer 1

Respuesta:

1 ) x - 3  = 3 - x

x + x = 3 + 3

2x = 6

x = 6 / 2

x = 3

3 - 3 = 3 - 3

0 = 0

2 ) 2x = x + 6x = 2 + 6 = 3- 12

2x - x - 6x = 3 - 12 - 2

- 5x = - 11

x = - 11 / - 5

x = 2.2

2 * 2.2 - 2.2 - 13.2 = - 11

4.4 - 2.2 - 13.2 = - 11

2.2 - 13.2 = - 11

- 11 = - 11

3 ) 1 + x + 2 = x + 3

x - x = 3 - 2 - 1

x = 0

1 + 0 + 2 = 0 + 3

3 = 3

x - 1 = x + 1

x - x = 1 + 1

x = 2

x = 1

5x - x - 3x = 1

x = 1
