Answer:
x = - [tex]\frac{3}{28}[/tex]
Step-by-step explanation:
Given
- [tex]\frac{2}{3}[/tex] x + [tex]\frac{3}{7}[/tex] = [tex]\frac{1}{2}[/tex]
Multiply through by 42 ( the LCM of 3, 7 and 2 ) to clear the fractions
- 28x + 18 = 21 ( subtract 18 from both sides )
- 28x = 3 ( divide both sides by - 28 )
x = - [tex]\frac{3}{28}[/tex]
