The sum of two numbers is 640. if you divide the bigger number by the smaller, you’ll get quotient 7 and remainder 64. find the numbers.

let 'x' and 'y' represent the two numbers and x>y

The sum of two numbers is 640:

x + y = 640

If you divide the bigger number by the smaller, you’ll get quotient 7 and remainder 64:

x = 7y + 64

by solving the system of equations:

x + y = 640

x = 7y + 64

we find:

x = 568

y = 72

i pretty sure it is

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
