Solve 66(z-4z)=39

$$66 ( z - 4 z ) = 39$$

Solve for z

$$z=-\frac{13}{66}\approx -0.196969697$$

Steps for Solving Linear Equation

Divide both sides by 66.

$$z-4z=\frac{39}{66}$$

Reduce the fraction \frac{39}{66} to lowest terms by extracting and canceling out 3.

$$z-4z=\frac{13}{22}$$

Combine z and -4z to get -3z.

$$-3z=\frac{13}{22}$$

Divide both sides by -3.

$$z=\frac{\frac{13}{22}}{-3}$$

Express \frac{\frac{13}{22}}{-3} as a single fraction.

$$z=\frac{13}{22\left(-3\right)}$$

Multiply 22 and -3 to get -66.

$$z=\frac{13}{-66}$$

Fraction \frac{13}{-66} can be rewritten as -\frac{13}{66} by extracting the negative sign.

$$z=-\frac{13}{66}$$
