Answer:
x = [tex]\frac{1}{10}[/tex]
Step-by-step explanation:
Given
3x - [tex]\frac{4}{5}[/tex] = - [tex]\frac{1}{2}[/tex]
Multiply through by 10, the lcm of 5 and 2 to clear the fractions
30x - 8 = - 5 ( add 8 to both sides )
30x = 3 ( divide both sides by 30 )
x = [tex]\frac{3}{30}[/tex] = [tex]\frac{1}{10}[/tex]
