Question

Which of the following is the solution to the equation 8(y + 3) = 2y ?

Answer 1

y = -1,5

Answer 2

There's number of ways to solve this

Answer 3

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

Answer 4

-1.5

Answer 5

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

Answer 6

that snot the final answer tho right?
