x+y=4
metodo grafico​ urgente para hoy

Step-by-step explanation:

Given

X+Y=4 -i

2X+Y=3 -ii

solving 1

X=4-Y -iii

equating eq iii and eq ii

2(4-y)+y=3

8-2y+y=3

-1y=3-8

-1y=-5

y=5

equating value of y in eq iii

x=4-y

x=4-5=-1

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
