Question

resolver las siguientes ecuaciones ​

Answer 1

Respuesta:

2× + 5 = 9

2× = -9-5

2× = -14

× = -14 / 2

× = -7

• 3× + 7 = 2× - 4

3× - 2× = 4 -7

1 × = -3

× = -3 / 1

× = -3

• 5× -9 = 3× +6

5× - 3× = -6 +9

2× = 3

× = 2 / 3

× = 0,66

• 2× -5 = 3× +4

2 × - 3× = -4 +5

-1× = 1

× = 1 / -1

× = -1

• 5× -1 = 7× -4

5× - 7× = 4 +1

-2× = 5

× = 5 / 2

× = 2.5
