Step-by-step explanation:

Answer 2

Answer:

The value of a should be - 5.

Step-by-step explanation:

According to question, the equation formed is -

• 2x + x - a = 5

Further solving the above equation, we get

➟ (2 + 1)x - a = 5

➟ (3)x - a = 5

➟ 3x - a = 5

After putting x = 0 (according to the question), we get

➟ 3(0) - a = 5

➟ - a = 5

➟ a = - 5
