Answer 1

Answer:

put the value of x as -2 in the given equation

x/-2=1

= x=-2 ( cross multiplication)

5 (-2)+4+2(-2)-7

now it's so simple you can solve it

Answer 2

$\blue\star$$\mathrm{we\: have\:to\: find\:x}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \frac{x}{ - 2} = 1$

$\: \: \: \: \: \: \: \: \: \: \: \: \: x = 1 \times ( - 2)$

$\: \: \: \: \: \: \: \: \: \: \: \: \: x = - 2$

$\mathrm{put\:the\: Value\:of\:x}$

$5x +4+2x-7$

$= 5( - 2)+4+2( - 2)-7$

$= ( - 10) + 4( - 4) - 7$

$= ( - 10) - 16 - 7$

$= - 26 - 7$

$= 33$
