Answer:
The digit is 75
Step-by-step explanation:
x is the digit in the tens place
y is the digit in the ones place.
We are given a system of equations
x + y = 12.... Equation 1
x - y = 2..... Equation 2
Subtract Equation 2 from Equation 1
2y = 10
y = 10/2
y = 5
x - y = 2
x - 5 = 2
x = 2 + 5
x = 7
Since:
x is the digit in the tens place
x = 7 = 7 × 10 = 70
y is the digit in the ones place
y = 5 = 5 × 1 = 5
Hence, The digit is 75
