Answer:

2s-c-b =a

Step-by-step explanation:

s = ( a+b+c)/2

Multiply each side by 2

2s = ( a+b+c)/2 *2

2s = a+b+c

Subtract c from each side

2s -c = a+b+c-c

2s -c = a+b

Subtract b from each side

2s-c-b = a+b-b

2s-c-b =a

Solve the system of linear equations.

irakobra [83]

Answer:

I would be our answer.

Step-by-step explanation:

So we need to solve both.

x-y=5 = 5.

And we also need to solve -x+y=5.

Let's regroup them.

$y-x=5$

Now we needt to subtract y from both sides.

$-x = 5 -y$

Now let's multiply both sides by -1.

$x = -5 + y$

Then we finally get

x = y - 5

Our final answer is I, there is no solution for this problem. Yes, they both equal 5 but do not fit any of the answers.

Thanks for using Brainly, have an amazing day.
