Answer:
Denominator = 9
[tex] x = 7 \frac{7}{8} [/tex]
Step-by-step explanation:
[tex] \frac{2}{9} x + \frac{2}{3} x = 7 \\ \\ \frac{2}{9} x + \frac{2 \times 3}{3 \times 3} x = 7 \\ \\ \frac{2}{9} x + \frac{6}{9} x = 7 \\ \\ \frac{2 + 6}{9} x = 7 \\ \\ \frac{8}{9} x = 7 \\ \\ x = 7 \times \frac{9}{8} \\ \\ x = \frac{63}{8} \\ \\ x = 7 \frac{7}{8} [/tex]
