The number=10x+y
we suggest this system of equations:
(10y+x)-(10x+y)=27
x+y=9 ⇒x=9-y
Can solve this system of equations by susbstitution method.
(10y+(9-y)-(10(9-y)+y)=27
10y+9-y-(90-10y+y)=27
10y-y+10y-y=27-9+90
18y=108
y=108/18
y=6
x=9-y
x=9-6
x=3
The number=10x+y=10(3)+6=36
Answer: the number is 36.
to check:
63-36=27
6+3=9
Answer:
-5
Step-by-step explanation:
The x and the y are the factors of the equation. Simply extract the value that is not the variable, and, well, you’ll get your constant.
Area is not a unit of measure. Foot and Yard are US customary units. Meter is the correct answer.
