2n-10<28
+10 +10 adding 10 to both sides to get the variable alone
2n<38
_____ divide both sides by 2 to get n by itself on one side
2
n<19
Check:
(2(18))-10<28
36-10<28
26<28 .......................IT WORKS!!!
You have to write two equation:
'substract 22 from a number'

and:
'the result is doubled, the answer is 6 more than the original number'

then you change 'Y' in 2nd equation for left side of 1st equation:

count it and you get:

This means that X=50
The original number is 50.
So the error is 1 mile
I ask what % of 15.5 = 1
How you write this;
x/100 *15.5 = 1
15.5x = 100
x = 100/15.5
x = 6.451629 round up 6.45
% error is 6.45 %
Answer:
X would be 1,000
