3+(3)/(2)x+4=4x-(5)/(2)x

We move all terms to the left:

3+(3)/(2)x+4-(4x-(5)/(2)x)=0

Domain of the equation: 2x!=0

x!=0/2

x!=0

x∈R

Domain of the equation: 2x)!=0We add all the numbers together, and all the variables

x!=0/1

x!=0

x∈R

3/2x-(+4x-5/2x)+3+4=0

We add all the numbers together, and all the variables

3/2x-(+4x-5/2x)+7=0

We get rid of parentheses

3/2x-4x+5/2x+7=0

We multiply all the terms by the denominator

-4x*2x+7*2x+3+5=0

We add all the numbers together, and all the variables

-4x*2x+7*2x+8=0

Wy multiply elements

-8x^2+14x+8=0

a = -8; b = 14; c = +8;

Δ = b^{2}-4ac

Δ = 14^{2}-4·(-8)·8

Δ = 452

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}$

The end solution:

$\sqrt{\Delta}=\sqrt{452}=\sqrt{4*113}=\sqrt{4}*\sqrt{113}=2\sqrt{113}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(14)-2\sqrt{113}}{2*-8}=\frac{-14-2\sqrt{113}}{-16} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(14)+2\sqrt{113}}{2*-8}=\frac{-14+2\sqrt{113}}{-16} $
