y = -1,5

There's number of ways to solve this

4. .Sam.

you know that $\large 2^3=8$ $8^{y + 3} = 2^y$ $2^{3(y + 3)} = 2^y$ 3(y+3)=y Solve

-1.5

$\begin{array}{l} \text{Expand out terms of the left hand side:} \\ 3 y+9=y \\ \text{Add }(-y-9)\text{ to both sides:} \\ 2 y=-9 \\ \text{Divide both sides by }2: \\ y=-\frac{9}{2} \\\end{array}$

that snot the final answer tho right?
