Question

13 bracket Z - 4 (close - 3) Z - 9 (close - 5) that + bracket close is equal to zero​

Answer 1

Answer:

z = 9

Step-by-step explanation:

13 (z - 4) - 3 (z - 9) - 5 (z + 4) = 0

13z - 52 - 3z + 27 - 5z - 20 = 0

13z - 3z - 5z - 52 + 27 - 20 = 0

13z - 8z - 72 + 27 = 0

5z - 45 = 0

5z = 0 + 45

5z = 45

z = 45/5

z = 9
