2zx+5-5x=-2
Subtract 5x from both sides.
2zx-5x=-2-5
Subtract 5 from both sides.
2zx-5x=-7
Subtract 5 from -2 to get -7.
\left(2z-5\right)x=-7
Combine all terms containing x.
\frac{\left(2z-5\right)x}{2z-5}=-\frac{7}{2z-5}
Divide both sides by 2z-5.
x=-\frac{7}{2z-5}
Dividing by 2z-5 undoes the multiplication by 2z-5.
2zx=5x-2-5
Subtract 5 from both sides.
2zx=5x-7
Subtract 5 from -2 to get -7.
2xz=5x-7
The equation is in standard form.
\frac{2xz}{2x}=\frac{5x-7}{2x}
Divide both sides by 2x.
z=\frac{5x-7}{2x}
Dividing by 2x undoes the multiplication by 2x.
z=\frac{5}{2}-\frac{7}{2x}
Divide 5x-7 by 2x.
