Question

Given the following formula, solve for a I WILL GIVE BRAINLIST!!

Answer 1

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

Answer 2

Answer:

a=2s-b-c

Step-by-step explanation:

2s=a+b+c

a=2s-b-c
