​

Answer 1

Answer:

a= -1

Step-by-step explanation:

Let's solve your equation step-by-step.

2a−5=8a+1

Step 1: Subtract 8a from both sides.

2a−5−8a=8a+1−8a

−6a−5=1

Step 2: Add 5 to both sides.

−6a−5+5=1+5

−6a=6

Step 3: Divide both sides by -6.

−6a/−6=6/−6

a=−1

Answer:

a=−1

Answer 2

Answer:

=> The value of a is -1.

Step-by-step explanation:

Given that:-

$2a- 5 = 8a +1$

To find:- The value of the expression,

For solving this expression, we must apply the transposition method:

As we have,

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

Now add both sides by $5$, we get

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

Simplifying it further, we get

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

Add the numbers,

=> $2a = 8a +6$

Subtract both sides by $8a$,

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

=> $-6a = 6$

Divide both sides by $-6$,

=> $a = -1$

Hence, the required solution is -1.
