8x-12=4(1/2x-6)
We move all terms to the left:
8x-12-(4(1/2x-6))=0
Domain of the equation: 2x-6))!=0We multiply all the terms by the denominator
x∈R
8x*2x-12*2x-6))-(4(1-6))=0
We add all the numbers together, and all the variables
8x*2x-12*2x-6))-(4(-5))=0
We add all the numbers together, and all the variables
8x*2x-12*2x=0
Wy multiply elements
16x^2-24x=0
a = 16; b = -24; c = 0;
Δ = b2-4ac
Δ = -242-4·16·0
Δ = 576
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{576}=24$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-24)-24}{2*16}=\frac{0}{32} =0 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-24)+24}{2*16}=\frac{48}{32} =1+1/2 $
