2x+3=3/4x-2

Solution for 2x+3=3/4x-2 equation:

2x+3=3/4x-2

We move all terms to the left:

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


Domain of the equation: 4x-2)!=0

x∈R


We get rid of parentheses

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

We multiply all the terms by the denominator


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

Wy multiply elements

8x^2+8x+12x-3=0

We add all the numbers together, and all the variables

8x^2+20x-3=0

a = 8; b = 20; c = -3;
Δ = b2-4ac
Δ = 202-4·8·(-3)
Δ = 496
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:

$\sqrt{\Delta}=\sqrt{496}=\sqrt{16*31}=\sqrt{16}*\sqrt{31}=4\sqrt{31}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(20)-4\sqrt{31}}{2*8}=\frac{-20-4\sqrt{31}}{16}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(20)+4\sqrt{31}}{2*8}=\frac{-20+4\sqrt{31}}{16}
