Question

Evaluate 3ac - a + b if
(1) a = 2, b = 1 and c = 4
(2) a = -2, b = 3 and c = 5

Answer 1

Gíѵєη :

• ❶ a = 2, b = 1 and c = 4
• ❷ a = -2, b = 3 and c = 5

Fíηɖ :

• 3ac - a + b

Sσłմէíση :

• ❶ a = 2, b = 1 and c = 4

Where,

❭❭ 3ac - a + b

Now -

➛ 3 ༝ 2 ༝ 4 - 2 + 1

➛ 24 - 2 + 1

➛ 25 - 2

➛ 23

∴

• Hence, the value is 23.

• ❷ a = -2, b = 3 and c = 5

Where,

❭❭ 3ac - a + b

Now -

➛ 3 ༝ (-2) ༝ 5 - (-2) + 3

➛ -6 ༝ 5 - (-2) + 3

➛ -6 ༝ 5 + 2 + 3

➛ -30 + 2 + 3

➛ -30 + 5

➛ -25

∴

• Hence, the value is -25.
