Answer:
[tex]y=26[/tex]
Step-by-step explanation:
[tex]\frac{13}{9}=\frac{y}{18}[/tex]
Cross multiply, isolate the variable, and divide by the coefficient to solve.
[tex]\frac{13}{9}=\frac{y}{18} \\ \\ 9y=234 \\ \\ y=26[/tex]
Plug back in to check.
[tex]\frac{13}{9}=1.4... \\ \\ \frac{26}{18}=1.4...[/tex]
