Answer:
Value of w is:
19
Step-by-step explanation:
We are given a equation:
12=w−|−7|
Modulus(|a|) gives us the absolute value of that number
i.e. if a is a positive number then, |a|=a
and if a is a negative number then |a|= -a
-7 is a negtaive number
so, |-7|= -(-7)=7
So, equation 12=w−|−7| is converted to
12= w-7
Adding 7 on both sides, we get
w= 19
Hence, Value of w is:
19
