Bx+6=6+15
Calculate the square root of 36 and get 6.
Bx+6=21
Add 6 and 15 to get 21.
Bx=21-6
Subtract 6 from both sides.
Bx=15
Subtract 6 from 21 to get 15.
xB=15
The equation is in standard form.
\frac{xB}{x}=\frac{15}{x}
Divide both sides by x.
B=\frac{15}{x}
Dividing by x undoes the multiplication by x.
