Answer:
Smaller number = 6
Larger number = 36
Step-by-step explanation:
Let the smaller number be x
Larger number = 4x + 12
Sum of two numbers = 42
x + 4x + 12 = 42 {Add like terms}
5x + 12 = 42 {Subtract 12 from both sides}
5x = 42 - 12
5x = 30 {Dive both sides by 5}
5x/5 = 30/5
x = 6
Smaller number = 6
Larger number = 4*6 + 12 = 24 + 12 = 36
