Answer:
t = 1.4
Step-by-step 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 <em>both</em> sides you keep the equation true.
<em>-5t = -4 - 3</em>
Combine like terms (subtract 3 from -4)
<em>-5t = -7</em>
-5t is essentially t x -5, (think of "<em>t</em>" as "1"), so in order to "get rid" of -5 and isolate <em>t</em>, you must divide both sides by -5. Think of dividing -5t by -5 as just -5/-5. It equals 1, leaving you with <em>t</em> on the left side.
Then, divide -7 by -5 on the right side to get your answer.
<em>-7 / -5 = 1.4</em>
Thus,
t = 1.4
