Answer: 12
Step-by-step explanation:
18÷3=6
6+6=12
18+12=30
30-18=12
Answer:
x=-8
y=4
Step-by-step explanation:
first you multiply this equation (-3x-2y=16) with negativ it will be like this 3x+2y=-16
3x+2y=-16
(x+9y=28)3 _multiply with 3
3x+2y=-16
3x+27y=84
use minus(-) =3x-3x=0
=2y-27y=-25y
=-16-84=-100
the result:-25y=-100
y=4
take any simple equation and replace y with 4
x+9y=28
x+9(4)=28
x+36=28
x=28-36
x=-8
answer:x=-8,y=4
Answer:
The solution of this system of linear equations is 
.
Step-by-step explanation:
Let be the following system of linear equations:
(1)
(2)
From (1) we clear 
:
And we apply this variable in (2):
And the value of is:
The solution of this system of linear equations is .
The second constraint is the same as the objective function, so your problem boils down to finding integer solutions to
.. 3x1 +5x2 = 36
There are 3 solutions. They are (x1, x2) = (12, 0), (7, 3), (2, 6)
The value of the objective function there is (obviously) 36.
