Question

The equation of the function is y=2x-3. Find the value of x when y= -5.

Answer 1

Given:

`y=2x-3`
`y=-5`

To determine the value of x, we first plug in y=-5 into y=2x-3:

`\begin{gathered} y=2x-3 \\ -5=2x-3 \\ Simplify\text{ and rearrange} \\ 2x=-5+3 \\ 2x=-2 \\ x=-(2)/(2) \\ Calculate \\ x=-1 \end{gathered}`

Therefore, the value of x is -1.
