Solve for the indicated variable in terms of the other variable. Explain how you arrived at your answer. -5x – 4y = 16; y =

Sagot :

-5x-4y=16
We add 4y to both sides.
-5x-4y+4y=16+4y
-5x=16+4y
We subtract 16 from both sides
-5x-16=16+4y-16
-5x-16=4y
We divide both sides by 4 so 
[tex]y= \frac{16-5x}{4} [/tex]
