Which of the following is the solution to the equation 8(y + 3) = 2y ?
There's number of ways to solve this
you know that \[\large 2^3=8\] \[8^{y + 3} = 2^y\] \[2^{3(y + 3)} = 2^y\] 3(y+3)=y Solve
\[\begin{array}{l} \text{Expand out terms of the left hand side:} \\ 3 y+9=y \\ \text{Add }(-y-9)\text{ to both sides:} \\ 2 y=-9 \\ \text{Divide both sides by }2: \\ y=-\frac{9}{2} \\\end{array}\]
that snot the final answer tho right?
