Let x= 1st# x+y=46
y= 2nd# x=2y+4
-2y
x+2y=4-> x+2y=4
x+y=46->*-2 +2x-2y=46
-x= 50
x= -50
x+y=46
-50+y=46
+50 +50
y=96

Find the square root of M.
In order to find the other number, we can use the relationship between the HCF and LCM. By multiplying the HCF and LCM together and dividing by one of the numbers, we can find the other number. So, (11 * 7700) / 275 = 308. Therefore, the other number is 308.

One number is 7, the other is 14. 7 + 14 = 21 4(7) = 2(14)
If the higher is 3 times the lower, the difference must be twice the lower so the numbers are 8 and 24.
There aren't any whole numbers that satisfy this.
