Sagot :
Answer:
presents = 346 , food = 174
Step-by-step explanation:
Let x = presents
y= food
x=2y-2
y= 520-x
y = 520-(2y-2)
y= 520 - 2y +2
2y+y= 520+2
3y = 522
y= 174
x=2y-2
x= 2(174) - 2
x= 348-2
x= 346
Answer:
presents = 346 , food = 174
Step-by-step explanation:
Let x = presents
y= food
x=2y-2

2y+y= 520+2
3y = 522
y= 174
x=2y-2
x= 2(174) - 2
x= 348-2
x= 346
