Question

Express y in terms of x. Then find the value of y when x= -1-3 (x + 2) = 5yY in terms of x:Y=

Answer 1

LEt's express y in term of x:

`\begin{gathered} -3(x+2)=5y \\ y=(-3(x+2))/(5) \end{gathered}`

Therefore:

`y=-(3)/(5)x-(6)/(5)`

Now, if x=-1, then we have:

`\begin{gathered} y=-(3)/(5)(-1)-(6)/(5) \\ =(3)/(5)-(6)/(5) \\ =-(1)/(5) \end{gathered}`

Therefore, if x=-1 then y=-1/5
