Question 1: <span>5z – 9 = 36
5z = 45
z = </span>
z = 9
Hence, the answer is D.
Question 2: <span>5(2z + 4) = 0
</span><span>
10z + 20 = 0
10z = -20
z = </span>
<span>
z = -2
Hence, the answer is A.
Question 3: 4a + 3(a + 1) = 24
4a + 3a + 3 = 24
7a = 21
a = </span>
a = 3
Hence, the answer is B.
Question 4: <span>3(4x + 5) = 12
12x + 15 = 12
12x = 12 - 15
12x = -3
x = </span>
Hence, the answer is A.
Question 5: <span>4x – 8 – 4x = 9
-8 </span>≠ 9
Hence, the answer is A.
