Answer:

Step-by-step explanation:
Step 1: Write out equation
a(t + z) = 45z + 67
Step 2: Distribute <em>a</em>
at + az = 45z + 67
Step 3: Subtract 67 on both sides
at + az - 67 = 45z
Step 4: Subtract az on both sides
at - 67 = 45z + az
Step 5: Factor out <em>z</em>
at - 67 = z(45 + a)
Step 6: Divide both sides by 45 + <em>a</em>
