25x+6\left(-z+102\right)-25z=675
Multiply both sides of the equation by 25.
25x+6\left(-z\right)+612-25z=675
Use the distributive property to multiply 6 by -z+102.
25x+612-25z=675-6\left(-z\right)
Subtract 6\left(-z\right) from both sides.
25x-25z=675-6\left(-z\right)-612
Subtract 612 from both sides.
25x=675-6\left(-z\right)-612+25z
Add 25z to both sides.
25x=675-6\left(-1\right)z-612+25z
Multiply -1 and 6 to get -6.
25x=675+6z-612+25z
Multiply -6 and -1 to get 6.
25x=63+6z+25z
Subtract 612 from 675 to get 63.
25x=63+31z
Combine 6z and 25z to get 31z.
25x=31z+63
The equation is in standard form.
\frac{25x}{25}=\frac{31z+63}{25}
Divide both sides by 25.
x=\frac{31z+63}{25}
Dividing by 25 undoes the multiplication by 25.
25x+6\left(-z+102\right)-25z=675
Multiply both sides of the equation by 25.
25x+6\left(-z\right)+612-25z=675
Use the distributive property to multiply 6 by -z+102.
6\left(-z\right)+612-25z=675-25x
Subtract 25x from both sides.
6\left(-z\right)-25z=675-25x-612
Subtract 612 from both sides.
6\left(-z\right)-25z=63-25x
Subtract 612 from 675 to get 63.
-6z-25z=63-25x
Multiply 6 and -1 to get -6.
-31z=63-25x
Combine -6z and -25z to get -31z.
\frac{-31z}{-31}=\frac{63-25x}{-31}
Divide both sides by -31.
z=\frac{63-25x}{-31}
Dividing by -31 undoes the multiplication by -31.
z=\frac{25x-63}{31}
Divide 63-25x by -31.
