Answer: z = [tex]\frac{67(1 - at)}{67a - 45}[/tex]
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 = [tex]\frac{67 - 67at}{67a - 45}[/tex]
= [tex]\frac{67(1 - at)}{67a - 45}[/tex]
