If it is a system of two unknowns:
1) 4x-8y=5 multiple by 3
2)6x-12y=10 multiple by -2
then
12x-24y=15
-12x+24y=-20
x and y equals 0, so
Answer: no solution
Answer:
Let ten's place digit =x and unit place digit =y
Number=10x+y
x+y=5 ...(i)
10x+y−9=10y+x
9x−9y=9x−y=1 ...(ii)
from (i) and (ii) we get,
x=3,y=2
∴Number=10×3+2=32.

Answer:
Both the angles are equal and opposite angles and are of 52°
Step-by-step explanation:
The two angles are equal and opposite angles.
So,
(3x-14)°=[4(x-9)]°
Putting the value of 'x', the angles are:
°
°
Both the angles are equal and opposite angles and are of 52°
Is to long to explain so I'm doing quite
find the triangle side so 2.1 square minus 1.4 square it is equal to 2.45
now you just multiple 2.45 by 2 because if you notice 2.45 is the triangle side that is missing and this is only the half so multiple by 2 for get the X value, I hope this helps you.
