Answer:
The value of (2x+y) is 3.
Step-by-step explanation:
First, we have to find the values of x and y.
We have that:
x + 2y = 9, which also means that:
x = 9 - 2y
Replacing into the second equation, to find y:
[tex]3x - y = -8[/tex]
[tex]3(9 - 2y) - y = -8[/tex]
[tex]27 - 6y - y = -8[/tex]
[tex]7y = 35[/tex]
[tex]y = \frac{35}{7}[/tex]
[tex]y = 5[/tex]
Finding x:
[tex]x = 9 - 2y = 9 - 10 = -1[/tex]
What is the value of (2x+y)?
2(-1) + 5 = -2 + 5 = 3
The value of (2x+y) is 3.
