Answer:
x = -4
Step-by-step explanation:
[tex]\frac{x}{3}[/tex] - [tex]\frac{5}{4}[/tex] = [tex]\frac{-31}{12}[/tex]
add 5/4 to both side
[tex]\frac{x}{3}[/tex] = [tex]\frac{-31}{12}[/tex] + [tex]\frac{5}{4}[/tex]
use common denominator 12 to add fraction
[tex]\frac{x}{3}[/tex] = [tex]\frac{-31 + 5*3}{12}[/tex]
[tex]\frac{x}{3}[/tex] = [tex]\frac{-31 + 15}{12}[/tex]
[tex]\frac{x}{3}[/tex] = [tex]\frac{-16}{12}[/tex]
multiply by 3 to both sides and solve
x = -4
