Answer:

x = $(-36)/(8)$ = -4.5

Step-by-step explanation:

WE are given with an equation and we have to solve it for the value of x

As the given equation is

$(-3)/(8)=(x)/(12)$

For this we have to use the rule of cross multiplication which states that

if we have two fractions such that

$(x)/(y)=(a)/(b)$

then by cross multiplication

b * x = a * y

so similarly for the given equation we have

$(-3)/(8)=(x)/(12)$

By cross multiplication

- 3 * 12 = 8 * x

multiplication gives

-36 = 8 x

Dividing both sides by 8

$(-36)/(8)=(8x)/(8)$

$(-36)/(8)=x$

So this is the answer in fraction in point form it would be

x = -4.5

x = 4.5 so it is 3/-8 = 4.5/12

Substiution method: y + 9 = 1/5x and45 - 3y = -15x

Please show work thank you very much.

Answers

y+9=1/5x menjadi y= 1/5x -9
sesudah ini sibtusika n dalam persamaan 4x - 5y = -15x
4x -5(1/5x-9)= -15 x
4x + x+45=-15x
5x +45 = -15x 45=-20x
x=-45/20
x= -9/4

y+9 =1/5x
y = 1/5(-9/4)-9
y = -189/20
(-9/4,-189/20)
