Answer:

t = 1.4

Explanation:

The goal is to isolate t, yeah?

First, move 3 to the left side by subtracting 3 from both sides. By subtracting it from both sides you keep the equation true.

-5t = -4 - 3

Combine like terms (subtract 3 from -4)

-5t = -7

-5t is essentially t x -5, (think of "t" as "1"), so in order to "get rid" of -5 and isolate t, you must divide both sides by -5. Think of dividing -5t by -5 as just -5/-5. It equals 1, leaving you with t on the left side.

Then, divide -7 by -5 on the right side to get your answer.

-7 / -5 = 1.4

Thus,

t = 1.4

Answer:

t=7/5

Explanation:

If you subtract 3 from each side, you end up with -5t=-7. In order to keep t isolated, you would have to divide -5 on both sides. When you do this, you will end up with t= -7/-5. You also need to simplify that. When simplified you end up with t=7/5. Hope this helps!
