(3/4)t=13

Solution for (3/4)t=13 equation:

(3/4)t=13

We move all terms to the left:

(3/4)t-(13)=0


Domain of the equation: 4)t!=0

t!=0/1

t!=0

t∈R


We add all the numbers together, and all the variables

(+3/4)t-13=0

We multiply parentheses

3t^2-13=0

a = 3; b = 0; c = -13;
Δ = b2-4ac
Δ = 02-4·3·(-13)
Δ = 156
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{156}=\sqrt{4*39}=\sqrt{4}*\sqrt{39}=2\sqrt{39}$
$t_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2\sqrt{39}}{2*3}=\frac{0-2\sqrt{39}}{6}
=-\frac{2\sqrt{39}}{6}
=-\frac{\sqrt{39}}{3}
$
$t_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2\sqrt{39}}{2*3}=\frac{0+2\sqrt{39}}{6}
=\frac{2\sqrt{39}}{6}
=\frac{\sqrt{39}}{3}
