400euros a month because 3,500x1.3687 would be 4790.45 and then divide by 12 to get 399.20 and you would round up because there is change
Answer: 3
Step-by-step explanation:
x + y = -9
x + 2y = -25
Rewrite the first equation as x = -9-y
Relace x in the second equation:
-9-y + 2y = -25
Simplify:
-9 +y = -25
Add 9 to both sides:
y = -16
Now you know y,, replace y in the first equation and solve for x:
x -16 = -9
Add 16 to both sides:
x = 7
Answer: x = 7
