6B\times 15+x=108
Multiply both sides of the equation by 6.
90B+x=108
Multiply 6 and 15 to get 90.
90B=108-x
Subtract x from both sides.
\frac{90B}{90}=\frac{108-x}{90}
Divide both sides by 90.
B=\frac{108-x}{90}
Dividing by 90 undoes the multiplication by 90.
B=-\frac{x}{90}+\frac{6}{5}
Divide 108-x by 90.
6B\times 15+x=108
Multiply both sides of the equation by 6.
90B+x=108
Multiply 6 and 15 to get 90.
x=108-90B
Subtract 90B from both sides.
