Answer :
SOLUTION
We want to know which of the options would give us
y = 34,
Let's try A. 8y = 9
This becomes
[tex]\begin{gathered} 8y=9 \\ to\text{ get y, we divide both sides by 8} \\ \frac{8y}{8}=\frac{9}{8} \\ y=1\frac{1}{8} \end{gathered}[/tex]We didn't get y = 34, hence A is incorrect.
Let's try B. y − 1= − 14
This becomes
[tex]\begin{gathered} y-1=-14 \\ \text{collecting like terms } \\ y=-14+1 \\ y=-13 \end{gathered}[/tex]B too is incorrect.
Let's try C. 4y = 6
[tex]\begin{gathered} 4y=6 \\ \text{divide both sides by 4 we have } \\ \frac{4y}{4}=\frac{6}{4} \\ y=\frac{3}{2} \\ y=1\frac{1}{2} \end{gathered}[/tex]C too is incorrect
Let's check D. 7 − y = 614
[tex]\begin{gathered} 7-y=614 \\ \text{collecting like terms we have } \\ y=7-614 \\ y=-607 \end{gathered}[/tex]D too is incorrect
