Answer:
400 +480 =880
Step-by-step explanation:
0+0=0
8+0=8
4+4=8
880
Step-by-step explanation:
let the 2 numbers be x and y.
x - 8 = y --(1)
5x = 2y - 8 --(2)
sub (1) into (2):
5x = 2(x - 8) - 8
5x = 2x - 24
3x = -24
x = -8
sub x = -8 into (1):
y = -8 - 8 = -16
first number is -8 and second number is -16.
