Question

67a(t+z)=45z+67 solve for (z)

Answer 1

Answer: z = $\frac{67(1 - at)}{67a - 45}$

Step-by-step explanation:

67a(t + z) = 45z + 67

67at + 67az = 45z + 67

-67at   -45z   -45z   -67at

 67az - 45z  =  67 - 67at

 z(67a - 45)  =  67 - 67at

÷ (67a - 45)  ÷ (67a - 45)

                 z  =  $\frac{67 - 67at}{67a - 45}$

                     =  $\frac{67(1 - at)}{67a - 45}$
