Ecuaciones

A) -2/3 z = 1

B) -2.5 = t/-4​

Answer 1

Respuesta:

A) - z = - 3/2

B) - t = 40

Explicación paso a paso:

A) -

2/3 z = 1

- 3/2 × ( - 2/3 )z = - 3/2 × 1

- 3/2 × ( - 2/3 )z = - 3/2

3/2 × 2/3z = - 3/2

1/2 × 2z = - 3/2

z = - 3/2

B) -

- 2 × 5 = t/-4

- 10 = t/-4

- 4 × ( - 10 ) = - 4 × t/-4

4 × 10 = - 4 × t/-4

40 = - 4 × t/-4

40 = 4 × t/4

40 = t

t = 40
