1/9(2m-16)=3/9(2m+4)

Solution for 1/9(2m-16)=3/9(2m+4) equation:

1/9(2m-16)=3/9(2m+4)

We move all terms to the left:

1/9(2m-16)-(3/9(2m+4))=0


Domain of the equation: 9(2m-16)!=0

m∈R



Domain of the equation: 9(2m+4))!=0

m∈R


We calculate fractions


(9m2/(9(2m-16)*9(2m+4)))+(-27m2/(9(2m-16)*9(2m+4)))=0


We calculate terms in parentheses: +(9m2/(9(2m-16)*9(2m+4))), so:

9m2/(9(2m-16)*9(2m+4))

We multiply all the terms by the denominator


9m2

We add all the numbers together, and all the variables

9m^2

Back to the equation:

+(9m^2)



We calculate terms in parentheses: +(-27m2/(9(2m-16)*9(2m+4))), so:

-27m2/(9(2m-16)*9(2m+4))

We multiply all the terms by the denominator


-27m2

We add all the numbers together, and all the variables

-27m^2

Back to the equation:

+(-27m^2)


We add all the numbers together, and all the variables

9m^2+(-27m^2)=0

We get rid of parentheses

9m^2-27m^2=0

We add all the numbers together, and all the variables

-18m^2=0

a = -18; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·(-18)·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
