X=-13
Because 9 plus 4 is 13 but x can't be negative so you divide my negative 1 and get x=-13
Answer:
y = 2/3 (21) + 20 (plug it in and multiply)
y = 14 +20 (add)
y = 34
(21,34)
Step-by-step explanation:
i hope this helps :)
No because 11 divided by 2 is not 5. the 11 would have to be 10
Answer:
3,14
Step-by-step explanation:
3x+5=6x-4
x=3
y=3x3+5
y=14
x,y=3,14
14=3x3+5
14=6x3-4
14=14
14=14
(x,y)=3,14
Answer:
Step-by-step explanation:
Let the 2 numbers be x and y
From the problem we have that
x * y = 600 and x + y = 59
From x + y = 59 -> x = 59 - y
Plug x = 59 - y to x * y = 600 we have
(59 - y) * y = 600
-> 59y - y^2 = 600
-> -y^2 + 59y - 600 = 0
-> y =
or 
Then we could plug the answers in and find x because x = 59 - y
