Answer :
Answer:
x = 7.2
Step-by-step explanation:
given the equation
5x + [tex]\frac{x}{3}[/tex] = 38.4
multiply each term by 3 to clear the fraction
3 (5x ) + 3 ( [tex]\frac{x}{3}[/tex] ) = 3 × 38.4
15x + x = 115.2
16x = 115.2 ← divide both sides by 16
[tex]\frac{16x}{16}[/tex] = [tex]\frac{115.2}{16}[/tex]
x = 7.2
