two numbers have an average of 2100 and one number is $425 more than the other number. What are the numbers
Let the first number be x and the second number be y. We're given two equations:
x + y = 2 * 2100
x + y = 4200
So we have our revised set of equations:
x + (x + 425) = 4200
Combining like terms, we get:
2x + 425 = 4200
Using our equation solver, we get:
x = 1887.5
Which means using equation (2), we get
y = 1887.5 + 425
y = 2312.5
Let the first number be x and the second number be y. We're given two equations:
- (x + y)/2 = 2100 (Average)
- y = x + 425
x + y = 2 * 2100
x + y = 4200
So we have our revised set of equations:
- x + y = 4200
- y = x + 425
x + (x + 425) = 4200
Combining like terms, we get:
2x + 425 = 4200
Using our equation solver, we get:
x = 1887.5
Which means using equation (2), we get
y = 1887.5 + 425
y = 2312.5
