Try this solution:
let the unknown two-digits number be 'xy'.
Then it is possible to write any two-digit number as 10x+y, where x - the tens digit and y - the unit digit.
Using the rule described above the phrase 'the tens digit of a number is twice the units digit' may be written as x=2y.
Using the same rule the phrase 'if the digits are reversed, the new number is 36 is less than the original number' may be written as (10x+y)-(10y+x)=36.
These two equations may be resolved as system of two equations:
Check: the original number is 84, the new number is 48; difference is 84-48=36.
answer: 84

Step-by-step explanation:
<em>Hey there!</em>
Well if the length is 18 and 3 inches we need to find the sum of both lengths,
18ft 3in + 18ft 3in = 36ft 6in
Width- 10ft 8in + 10ft 8in = 20ft 16 in -> 21ft 4in
l + w = 57ft 10in

Answer:
Step-by-step explanation:
Move x / 4 to left hand side and change its sign
Similarly, move 2 to right hand side and change it's sign
Take the L.C.M of 3 and 4
L.C.M of 3 and 4 = 12
Subtract 2 from 3
Do cross multiplication
--------------------------------------------------------------------
Distribute 3 through the parentheses
Move x to left hand side and change it's sign
Similarly, move 12 to right hand side and change it's sign
Collect like terms
Subtract 12 from 33
Divide both sides by 7
Calculate
