Question

Solve the equation 2a-5 = 8a+1

Answer 1

Answer:

-1

Step-by-step explanation:

$2a-8a \\ -6a=6 \\ a = \frac{6}{6}= - 1$

Answer 2

Answer:

The value of a is -1.

Step-by-step explanation:

According to the data given in the question,

We have to find the value of the equation,

Given that,

2a - 5 = 8a + 1

Here we will use the transposition method,

Now, add both sides by 5:

=> 2a - 5 + 5 = 8a + 1 + 5

Simplifying it further, we get

=> 2a = 8a + 6

Subtract both sides by 8a,

=> 2a - 8a = 8a + 6 - 8a

=> -6a = 6

Divide both sides by -6,

=> a = -1

Hence, the required solution will be -1.
