-1/2x+3=3/4x-2
We move all terms to the left:
-1/2x+3-(3/4x-2)=0
Domain of the equation: 2x!=0
x!=0/2
x!=0
x∈R
Domain of the equation: 4x-2)!=0We get rid of parentheses
x∈R
-1/2x-3/4x+2+3=0
We calculate fractions
(-4x)/8x^2+(-6x)/8x^2+2+3=0
We add all the numbers together, and all the variables
(-4x)/8x^2+(-6x)/8x^2+5=0
We multiply all the terms by the denominator
(-4x)+(-6x)+5*8x^2=0
Wy multiply elements
40x^2+(-4x)+(-6x)=0
We get rid of parentheses
40x^2-4x-6x=0
We add all the numbers together, and all the variables
40x^2-10x=0
a = 40; b = -10; c = 0;
Δ = b2-4ac
Δ = -102-4·40·0
Δ = 100
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{100}=10$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-10)-10}{2*40}=\frac{0}{80} =0 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-10)+10}{2*40}=\frac{20}{80} =1/4 $
