Answer
$y = 4$
Work Step by Step
We fist combine like terms to obtain the equation:
$-1 = -2y + 7$
We need to isolate the variable $y$ by subtracting $7$ from both sides as shown below:
$-1 - 7 = -2y + 7 - 7$
Simplifying we have:
$-8 = -2y$
We now divide through by the coefficient of the variable $y$ as shown below:
$\frac{-8}{-2} = \frac{-2}{-2}y$
Simplify to get:
$4 = y$
Rearranging, we have:
$y = 4$
Therefore, the equation will have a possible solution at $y = 4$
