Answer:
x= 30, y= 90
Step-by-step explanation:
Let the smaller number be x and the greater number be y.
Given that the sum of the 2 numbers is 120,
x +y= 120 -----(1)
The greater number is 3 times the smaller number:
y= 3x -----(2)
Substitute (2) into (1):
x +3x= 120
Simplify:
4x= 120
x= 120 ÷4 (÷4 on both sides)
x= 30
Substitute x= 30 into (2):
y= 3(30)
y= 90
Answer:
Let the first number be x
Then the second number will be 3 × x = 3x
According to the question
3x + x = 120
4x = 120
Taking 4 to RHS
x = 120/4
x = 30
Number are
x = 30
3x = 3(30) = 90
