Answer:

-78.4

Explanation:

Given the expression

[tex]9.1+\frac{y}{7}=-2.1[/tex]

Multiply through by 7:

[tex]\begin{gathered} 7(9.1)+y\text{ = 7(-2.1)} \\ 63.7+y=-14.7 \end{gathered}[/tex]

Subtract 63.7 from both sides

[tex]\begin{gathered} 63.7+y-63.7=-14.7-63.7 \\ y=-78.4 \end{gathered}[/tex]

Hence the value of y is -78.4
