Question

the sum of two numbers is 68.the smaller number is 8 less than the larger number what are the numbers​

Answer 1

Smaller number = 30

Larger number = 38

Explanation:

68 = (x+8) + x

68 = 2x - 8

60 = 2x

30 = x

and

68 = (x-8) + x

68 = 2x - 8

76 = 2x

38 = x

Answer 2

30 and 38

Explanation:

If x is the smaller number and y is the larger number:

x + y = 68

x = y - 8

Solve with substitution:

y - 8 + y = 68

2y = 76

y = 38

x = 30

So the two numbers are 30 and 38.
