The sum of two numbers is 57. The larger number is three less than four times the smaller number. Find the numbers pls help i am timed

The numbers are 10.8 and 46.2.

Step-by-step explanation: The sum of two numbers is 57.

x + y = 57

Assume x is the larger number.

x - 3 = 4y

x = 4y + 3

Use subsitution.

4y + 3 + y = 57

y = -4y - 3 + 57

y = -4y + 54

5y = 54

y = 10.8

Plug in y.

x + 10.8 = 57

x = 46.2

Check.

46.2 - 3 = 4(10.8)

43.2 = 43.2

10.8 and 46.2.
