Question

the value of z is: -19*(4+(-2))= -19*4+(-19)*z

Answer 1

According to the question

$- 19 \times (4 + ( - 2)) = - 19 \times 4 + (-19) \times z$

Making it simple as

$- 19 \times(4 - 2) = - 19 \times 4 - 19 \times z$

$- 19 \times 2 = - 76 - 19z$

$- 38 = - 76 - 19z$

$- 38 + 76 = - 19z$

$38 = - 19z$

$z = \frac{38}{ - 19}$

$z = - 2$
