help me plzzzz...... .

Answer:
x = [tex]\frac{-36}{8}[/tex] = -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
[tex]\frac{-3}{8}=\frac{x}{12}[/tex]
For this we have to use the rule of cross multiplication which states that
if we have two fractions such that
[tex]\frac{x}{y}=\frac{a}{b}[/tex]
then by cross multiplication
b * x = a * y
so similarly for the given equation we have
[tex]\frac{-3}{8}=\frac{x}{12}[/tex]
By cross multiplication
- 3 * 12 = 8 * x
multiplication gives
-36 = 8 x
Dividing both sides by 8
[tex]\frac{-36}{8}=\frac{8x}{8}[/tex]
[tex]\frac{-36}{8}=x[/tex]
So this is the answer in fraction in point form it would be
x = -4.5
