Answer:
x = 10
y = 5
Step-by-step explanation:
Let the two numbers be x and y
Difference between the two is 10
x-y = 10
Sum;
x+ y is four times the smallest number
Let the smaller number be y
x+ y = 4y
Subtracting equation ii from i
-2y = 10 -4y
4y-2y = 10
2y = 10
y = 10/2
y = 5
Recall;
x-y = 10
x = 10 + y
x = 10 + 5 = 15
