x/(1.23-x)=1.5
We move all terms to the left:
x/(1.23-x)-(1.5)=0
Domain of the equation: (1.23-x)!=0We add all the numbers together, and all the variables
We move all terms containing x to the left, all other terms to the right
-x!=-1.23
x!=-1.23/-1
x!=1+0.23/1
x∈R
x/(-1x+1.23)-(1.5)=0
We add all the numbers together, and all the variables
x/(-1x+1.23)-1.5=0
We multiply all the terms by the denominator
x-(1.5)*(-1x+1.23)=0
