Answer:
14 months
Step-by-step explanation:
14x3=42
42+90= 132
10x+y = 10y+x +36
x+y=14
9x-9y=36
x-y=4
x= 14-y
14-2y==4
10=2y
y=5
x=9
Answer:
Integer 1 is x
Integer 2 is y
x + y = -31
x - y = -55
Add:
2x = -86
x = -43
Substitute:
-43 + y = -31
y = 12
Therefore, the two integers are: 12 and -43
30x² - 5 monomial
