Question

help me solve 14-4y < (with the line) 66
a) y >(with the line ) -13
b) y >-17
c) y> (with the line)-17
d)y >-13

Answer 1

add 4y to both sides

Answer 2

\[14 - 4y \le66\]

add 4y to both sides.....then subtract 66 from both sides....and finally divide both sides by 4...what do you get?

Answer 3

We do this to isolate 'y' because that is what we are solving for

\[14 - 4y \le 66\]

after adding 4y to both sides we have

\[14 \le 66 + 4y\]

then we subtract 66 from both sides

\[-52 \le 4y\]

and we finally divide both sides by 4 to completely isolate 'y'

\[\frac{ -52 }{ 4 } \le \frac{ 4y }{ 4 }\]

simplified down a bit

\[y \ge \frac{ -52 }{ 4 }\]

so what does that equate to?

Answer 4

-13

Answer 5

so its a

Answer 6

Right it simplifies down to

\[y \ge -13\]

So yes...answer choice A :)
