Answer:
a = 1.9
Explanation:
We can solve for a using the following steps:
Step 1: Subtract 7.93 from both sides:
(3a + 8.5 = 3.3a + 7.93) - 7.93
3a + 0.57 = 3.3a
Step 2: Subtract 3a from both sides:
(3a + 0.57 = 3.3a) - 3a
0.57 = 0.3a
Step 3: Divide both sides by 0.3 to solve for a:
(0.57 = 0.3a) / 0.3
1.9 = a
Therefore, a = 1.9.
