Question

Solve.

–4t ≤ 48

Answer 1

Isolate T.
Divide both sides by -4
-4t/-4 < 48/-4

Answer 2

Remember when you divide by a negative you flip the signs.

Answer 3

-4t <= 48

-t <= 48/4

-t <= 12

Now when we multiply an inequality with -1, we REVERSE THE INEQUALITY SIGN.

-t * -1 >= -12

t >= -12

Understood? :)

Answer 4

@AkashdeepDeb T wasn't negative, 4 was. when you divided you canceled out -4

Answer 5

It does not really matter @tHe_FiZiCx99

It is the same if you take the constants separately or together.
It is for better explanation.

Answer 6

@AkashdeepDeb I guess that works, but it makes it more simple. :p

Answer 7

So it's t ≥ –12
