Answer 2

Answer:

The value of a = -1/2

Step-by-step explanation:

here, $\frac{a + 3}{\frac{1}{2}} = 5$

now, simplify it first

      = $\frac{2(a + 3)}{1} = 5$

      = $2a + 6 = 5$

By hit and trial method

Let's take the number one by one.

2  ⇒ 2 × 2 + 6 = 5         ⇒ 10 ≠ 5

1   ⇒ 2 × 1 + 6 = 5          ⇒ 8 ≠ 5

0 ⇒ 2 × 0 + 6 = 5          ⇒ 6 ≠ 5

-2 ⇒ 2 × -2 + 6 = 5        ⇒ 2 ≠ 5

-1  ⇒ 2 × -1 + 6 = 5         ⇒ 4 ≠ 5

but it will come by -1/2.

so, I directly do that because it will go very long.

-1/2 ⇒ 2 × -1/2 + 6 = 5    ⇒ 5 = 5

∴ The value of a = -1/2.

hope it will help you.
