5bx^{2}-mn-4bx^{2}=p
Subtract 4bx^{2} from both sides.
bx^{2}-mn=p
Combine 5bx^{2} and -4bx^{2} to get bx^{2}.
bx^{2}=p+mn
Add mn to both sides.
x^{2}b=mn+p
The equation is in standard form.
\frac{x^{2}b}{x^{2}}=\frac{mn+p}{x^{2}}
Divide both sides by x^{2}.
b=\frac{mn+p}{x^{2}}
Dividing by x^{2} undoes the multiplication by x^{2}.
-mn=p+4bx^{2}-5bx^{2}
Subtract 5bx^{2} from both sides.
-mn=p-bx^{2}
Combine 4bx^{2} and -5bx^{2} to get -bx^{2}.
\left(-n\right)m=p-bx^{2}
The equation is in standard form.
\frac{\left(-n\right)m}{-n}=\frac{p-bx^{2}}{-n}
Divide both sides by -n.
m=\frac{p-bx^{2}}{-n}
Dividing by -n undoes the multiplication by -n.
m=-\frac{p-bx^{2}}{n}
Divide p-bx^{2} by -n.
5bx^{2}-mn-4bx^{2}=p

Divide both sides by x^{2}.
b=\frac{mn+p}{x^{2}}
Dividing by x^{2} undoes the multiplication by x^{2}.
-mn=p+4bx^{2}-5bx^{2}
Subtract 5bx^{2} from both sides.
-mn=p-bx^{2}
Combine 4bx^{2} and -5bx^{2} to get -bx^{2}.
\left(-n\right)m=p-bx^{2}
The equation is in standard form.
