X=30+5(x/60)

Solution for X=30+5(x/60) equation:

X=30+5(X/60)

We move all terms to the left:

X-(30+5(X/60))=0

We add all the numbers together, and all the variables

X-(30+5(+X/60))=0

We multiply all the terms by the denominator


X*60))-(30+5(+X=0

We add all the numbers together, and all the variables

X+X*60))-(30+5(=0

Wy multiply elements

60X^2+X=0

a = 60; b = 1; c = 0;
Δ = b2-4ac
Δ = 12-4·60·0
Δ = 1
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1}=1$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-1}{2*60}=\frac{-2}{120}
=-1/60
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+1}{2*60}=\frac{0}{120}
=0
