(99-x)/(100-x)=0.98
We move all terms to the left:
(99-x)/(100-x)-(0.98)=0
Domain of the equation: (100-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!=-100
x!=-100/-1
x!=+100
x∈R
(-1x+99)/(-1x+100)-(0.98)=0
We add all the numbers together, and all the variables
(-1x+99)/(-1x+100)-0.98=0
We multiply all the terms by the denominator
(-1x+99)-(0.98)*(-1x+100)=0
We get rid of parentheses
-1x-(0.98)*(-1x+100)+99=0
We move all terms containing x to the left, all other terms to the right
-1x-(0.98)*(-1x+100)=-99
