Translate: 16 more than a number is three less than twice that number

We have to make the sentences to be algebraic format
for example, n is the number
16 + n = 2n - 3
This is the equation

If you need to find what is n, then solve the equation
I classified number with number, coefficient-variable with coefficient-variable.
16 + n = 2n - 3
n - 2n = -3 - 16
-n = -19
n = 19
This is the value of n

Step-by-step explanation:

•••••for 12+4=4, solution is null

•••••but for x^2-49=0

x^2=49

i.e,x=±7

clearly ,2nd/B is correct option
