1/3(m+21)=2/3m=-2

Solution for 1/3(m+21)=2/3m=-2 equation:

1/3(m+21)=2/3m=-2

We move all terms to the left:

1/3(m+21)-(2/3m)=0


Domain of the equation: 3(m+21)!=0

m∈R



Domain of the equation: 3m)!=0

m!=0/1

m!=0

m∈R


We add all the numbers together, and all the variables

1/3(m+21)-(+2/3m)=0

We get rid of parentheses

1/3(m+21)-2/3m=0

We calculate fractions


3m/(9m^2+189m)+(-6mm/(9m^2+189m)=0


We calculate terms in parentheses: +(-6mm/(9m^2+189m), so:

-6mm/(9m^2+189m

We multiply all the terms by the denominator


-6mm

Back to the equation:

+(-6mm)


We get rid of parentheses

3m/(9m^2+189m)-6mm=0

We multiply all the terms by the denominator


3m-6mm*(9m^2+189m)=0

We multiply parentheses

-54m^3-1134m^2+3m=0

We do not support empression: m^3
