Question

use the equation below to find a, if b = 13 and c = 17.
a = 39 - b - c

Explanation:

Step1: Substitute given values

Substitute $b = 13$ and $c = 17$ into $a=39 - b - c$. So we get $a = 39-13 - 17$.

Step2: First subtraction

Calculate $39-13=26$. Then the expression becomes $a = 26-17$.

Step3: Final subtraction

Calculate $26 - 17=9$.

Answer:

$a = 9$
