If the number is x, then 2*(x+3)-7=9 due to that you subtract the result of double of x+3. Adding 7 to both sides, we get 2*(x+3)=16. Next, we divide both sides by 2 to get x+3=8 and subtract 3 from both sides for our final result, x=5

Answer fast? What?
x + 2y = 17...Equation A
8x + 3y = 45...Equation B
Solve A for x.
x = 17 - 2y
Plug this into B to solve for y.
8(17 - 2y) + 3y = 45
136 - 16y + 3y = 45
136 - 13y = 45
-13y = 45 - 136
-13y = -91
y = -91/-13
y = 91/13
y = 7
To find y, plug x = 7 into either equation to find x.
I will use Equation A.
x + 2y = 17
x + 2(7) = 17
x + 14 = 17
x = 17 - 14
x = 3
Answer: x = 3, y = 7
