Question

What is the solution set for 6x-9=15, given the replacement set {0,1,2,3,4}?

Answer 1

To solve the equation, we first add 9 to both sides:

`\begin{gathered} 6x-9=15 \\ 6x-9+9=15+9 \\ 6x=24 \end{gathered}`

Now, we divide by 6 from both sides of the equation:

`\begin{gathered} (6x)/(6)=(24)/(6) \\ $$\boldsymbol{x=4}$$ \end{gathered}`

Therefore, the solution for the given equation is x = 4.
