Question

x/4+4=11 by trial and error method​

Answer 1

Step-by-step explanation:

Let

us plug in some values for X to check if it's true or not.

X/4+4=11

let's put 32 in place of X

which gives 8+4=12

This does not work but we know that now X must be smaller than 32

let's put 24 in place of X then

Then the answer is 10

We are just one number behind

32 doesn't work and 24 doesn't work

So the correct solution must lie somewhere between them

Finally we get that X=28

$28 \div 4 + 4 = 11$

7+4=11

11=11
