Answer
The solution is $\frac{3}{25}$
Work Step by Step
-4z = -$\frac{12}{25}$ Multiply both sides by -$\frac{1}{4}$
-4$\times$$\frac{1}{4}$z = -$\frac{12}{25}$ $\times$ -$\frac{1}{4}$
z= $\frac{12\times1}{25\times4}$
z= $\frac{12}{100}$
z= $\frac{4\times3}{4\times25}$
z= $\frac{3}{25}$
The solution is $\frac{3}{25}$
Check
Replace z with $\frac{3}{25}$
-4z=-$\frac{12}{25}$
-4$\times$$\frac{3}{25}$=-4z=-$\frac{12}{25}$
-$\frac{4\times3}{25}$=-$\frac{12}{25}$
-$\frac{12}{25}$ =-$\frac{12}{25}$
