40xy+2xy=4
Multiply 8 and 5 to get 40.
42xy=4
Combine 40xy and 2xy to get 42xy.
42yx=4
The equation is in standard form.
\frac{42yx}{42y}=\frac{4}{42y}
Divide both sides by 42y.
x=\frac{4}{42y}
Dividing by 42y undoes the multiplication by 42y.
x=\frac{2}{21y}
Divide 4 by 42y.
40xy+2xy=4
Multiply 8 and 5 to get 40.
42xy=4
Combine 40xy and 2xy to get 42xy.
\frac{42xy}{42x}=\frac{4}{42x}
Divide both sides by 42x.
y=\frac{4}{42x}
Dividing by 42x undoes the multiplication by 42x.
y=\frac{2}{21x}
Divide 4 by 42x.
