Let x=number
1st condition: 7x, seven times the number
2nd condition: 2x, twice the number
3rd condition ---> ADD = 63 ---system%287x%2C2x%2C63%29
Continuing,
7x%2B2x=63
9x=63 ------> cross%289%29x%2Fcross%289%29=cross%2863%297%2Fcross%289%29
x=7 ANSWER
Check via the 3 conditions ---->7%2A7=49,2%2A7=14---Addition, 49+14=63
Thank you,
