Answer:
[tex] y = 2 \frac{1}{2} [/tex]
Step-by-step explanation:
[tex]y + 6 \frac{1}{2} = 9 \\ \\ y + \frac{6 \times 2 + 1}{2} = 9 \\ \\ y + \frac{12 + 1}{2} = 9 \\ \\ y + \frac{13}{2} = 9 \\ \\ y = 9 - \frac{13}{2} \\ \\ y = \frac{9 \times 2 - 13}{2} \\ \\ y = \frac{18 - 13}{2} \\ \\ y = \frac{5}{2} \\ \\ y = 2 \frac{1}{2} [/tex]
