X = 51
Y = 12
Step-by-step explanation:
2 numbers: (Larger) Number 1 is x and Number 2 is y
The equation is x + y = 63

Combine like variables:
Solve:
- 4y + 15 - 15 = 63 - 15
- 4y = 48
Divide 4 from each side:
To find x fill in the variables from the 'x =' equation:
- x = 3y + 15
- x = 3( 12) + 15
- <em><u>x = 51</u></em>
