Z = 8 + 6x -px for x
NeTakaya

Answer:

x=\frac{z-8}{-p+6}

Step-by-step explanation:

Flip the equation.

−px+6x+8=z

Add -8 to both sides.

−px+6x+8+−8=z+−8

−px+6x=z−8

Factor out variable x.

x(−p+6)=z−8

Divide both sides by -p+6.

\frac{x(-p+6)}{-p+6} =\frac{z-8}{-p+6}

x=\frac{z-8}{-p+6}

hope this helps
