let first number = x
second number = y

The sum of two integers is 143 and their difference is 47.
x + y = 143

The sum of two integers is 143 and their difference is 47.
x - y = 47

SOLVE:
x = 143 - y
x - y = 47

substitute
143 - y -y =47
143 -47 = 2y
y = 48

substitute
x + 48 = 143
x=95

therefore the two numbers are 48 and 95
