(7/6)v=35

Solution for (7/6)v=35 equation:

(7/6)v=35

We move all terms to the left:

(7/6)v-(35)=0


Domain of the equation: 6)v!=0

v!=0/1

v!=0

v∈R


We add all the numbers together, and all the variables

(+7/6)v-35=0

We multiply parentheses

7v^2-35=0

a = 7; b = 0; c = -35;
Δ = b2-4ac
Δ = 02-4·7·(-35)
Δ = 980
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{980}=\sqrt{196*5}=\sqrt{196}*\sqrt{5}=14\sqrt{5}$
$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-14\sqrt{5}}{2*7}=\frac{0-14\sqrt{5}}{14}
=-\frac{14\sqrt{5}}{14}
=-\sqrt{5}
$
$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+14\sqrt{5}}{2*7}=\frac{0+14\sqrt{5}}{14}
=\frac{14\sqrt{5}}{14}
=\sqrt{5}
