What is equivalent to -1/3t=4/3​
stepan [7]

<u>Answer:</u>

The equivalent of -1/3t = 4/3​ is t = -4

<u>Solution:</u>

Need to determine such value of t so that when it is multiplied by -1/3, we should get 4/3

That is we need to solve following expression for value of t.

-\frac{1}{3} t=\frac{4}{3}

On multiplying both the sides by 3 we get

\begin{array}{l}{-\frac{1}{3} t \times 3=\frac{4}{3} \times 3} \\\\ {=>-t=4}\end{array}

Now multiplying both the sides by -1 we get

\begin{array}{l}{-t \times-1=4 \times-1} \\ {=>t=-4}\end{array}

Let’s recheck the value of t

-\frac{1}{3} t=-\frac{1}{3} \times-4=\frac{4}{3}

Hence for t = -4, expression -1/3 t is equal to 4/3.
