The sum of two numbers is 92, if one number is three times the other number plus 4. Find the value of the 2 numbers.
Question
Answer:
Answer: Two numbers are 70 and 22.
Step by step explanation:
Let's call the two numbers "x" and "y." According to the information given, we have two pieces of information:
1. The sum of the two numbers is 92:
x + y = 92
2. One number is three times the other number plus 4:
x = 3y + 4
Now, we can solve this system of linear equations. We can substitute the second equation into the first equation:
(3y + 4) + y = 92
Now, combine like terms:
4y + 4 = 92
Subtract 4 from both sides:
4y = 92 - 4
4y = 88
Now, divide by 4 to find the value of y:
y = 88 / 4
y = 22
Now that we have found the value of y, we can use it to find the value of x using the second equation:
x = 3y + 4
x = 3(22) + 4
x = 66 + 4
x = 70
So, the two numbers are x = 70 and y = 22, and they add up to 92, as required.
