Given the following formula solve for a <br><br>s = a+b+c/2

Hatshy [7]

Answer:

$a=2s-b-c$

Step-by-step explanation:

Given formula:

$s=\frac{a+b+c}{2}$

To solve for $a$

In order to solve for $a$ we will try to isolate $a$ on one side of the equation.

Steps to isolate $a$ .

1) Multiplying both sides by $2$ to remove fractions.

$2\times s=2\times \frac{a+b+c}{2}$

$2s=a+b+c$

2) Subtracting both sides by $b$

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

$2s-b=a+c$

3) Subtracting both sides by $c$

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

$2s-b-c=a$

Thus, we successfully isolated $a$ on one side. The formula for $a$ can be given as:

∴ $a=2s-b-c$
