30\times 6x\sqrt{25}=x_{85}
Multiply both sides of the equation by 6.
180x\sqrt{25}=x_{85}
Multiply 30 and 6 to get 180.
180x\times 5=x_{85}
Calculate the square root of 25 and get 5.
900x=x_{85}
Multiply 180 and 5 to get 900.
\frac{900x}{900}=\frac{x_{85}}{900}
Divide both sides by 900.
x=\frac{x_{85}}{900}
Dividing by 900 undoes the multiplication by 900.
30\times 6x\sqrt{25}=x_{85}
Multiply both sides of the equation by 6.
180x\sqrt{25}=x_{85}
Multiply 30 and 6 to get 180.
180x\times 5=x_{85}
Calculate the square root of 25 and get 5.
900x=x_{85}
Multiply 180 and 5 to get 900.
x_{85}=900x
Swap sides so that all variable terms are on the left hand side.
