m^{2}x-m^{2}+2=m\left(2x-1\right)
Use the distributive property to multiply m^{2} by x-1.
m^{2}x-m^{2}+2=2mx-m
Use the distributive property to multiply m by 2x-1.
m^{2}x-m^{2}+2-2mx=-m
Subtract 2mx from both sides.
m^{2}x+2-2mx=-m+m^{2}
Add m^{2} to both sides.
m^{2}x-2mx=-m+m^{2}-2
Subtract 2 from both sides.
\left(m^{2}-2m\right)x=-m+m^{2}-2
Combine all terms containing x.
\left(m^{2}-2m\right)x=m^{2}-m-2
The equation is in standard form.
\frac{\left(m^{2}-2m\right)x}{m^{2}-2m}=\frac{\left(m-2\right)\left(m+1\right)}{m^{2}-2m}
Divide both sides by m^{2}-2m.
x=\frac{\left(m-2\right)\left(m+1\right)}{m^{2}-2m}
Dividing by m^{2}-2m undoes the multiplication by m^{2}-2m.
x=1+\frac{1}{m}
Divide \left(-2+m\right)\left(1+m\right) by m^{2}-2m.
m^{2}x-m^{2}+2=m\left(2x-1\right)
Use the distributive property to multiply m^{2} by x-1.
m^{2}x-m^{2}+2=2mx-m
Use the distributive property to multiply m by 2x-1.
m^{2}x-m^{2}+2-2mx=-m
Subtract 2mx from both sides.
m^{2}x+2-2mx=-m+m^{2}
Add m^{2} to both sides.
m^{2}x-2mx=-m+m^{2}-2
Subtract 2 from both sides.
\left(m^{2}-2m\right)x=-m+m^{2}-2
Combine all terms containing x.
\left(m^{2}-2m\right)x=m^{2}-m-2

x=\frac{\left(m-2\right)\left(m+1\right)}{m^{2}-2m}
Dividing by m^{2}-2m undoes the multiplication by m^{2}-2m.
x=1+\frac{1}{m}
Divide \left(-2+m\right)\left(1+m\right) by m^{2}-2m.
