Aug 16, 2016

y = 3

Explanation:

-4y = 4 - 16 (subtract 16 from both sides)
-4y = -12 (simplify RHS)
y = 3 (divide both sides by -4)

$y = 3$

Explanation:

To solve this equation, isolate the - 4y term on the left of the equation while having numeric values on the right.

To do this, subtract 16 from both sides.

$\Rightarrow - 4 y \cancel{+ 16} \cancel{- 16} = 4 - 16$

we are left with $- 4 y = - 12$

now divide both sides by - 4.

$\frac{{\cancel{- 4}}^{1} y}{\cancel{- 4}} ^ 1 = \frac{- 12}{- 4} \Rightarrow y = 3 \text{ is the solution}$
