First we have to setup system of equations for the given case.
Let x is the original number and y is the reverse three digit number.
Then,
x+y=665 Equation 1
x-y=297 Equation 2
Add both equations to get.
2x=962
Divide both sides by 2.
x=481
This is the original number. And reverse number is : 481+y=962
y=184
Here Hundredth digit is 4, and tenth digit is 8 which is 2 times of the hundredth digit.
Answer: Number is 481
The answer to <em>5 + 3r = 5r - 19 </em>is <em>r = 12</em>.
Answer: No solution
Step-by-step explanation:
1. Expand the brackets- 9-3x+5x=2x+4
2. Add common terms- 9+2x=2x+4
3. Subtract 2x from both sides- 9=4
4. Nine cannot equal four and therefore, there is no solution.
