Answer:
12
Step-by-step explanation:
assuming you wish to evaluate the expression.
substitute x = 5 into the expression
=
=
= 12
You have to use the distributive property, therefore you get 2x+13/3.
The next step is to do 2 x 5 because they gave us a number for the variable x. Then you have to do 2 x 13 which gives us 26.
10+26=36 and 36/3=12, hope I helped, Have a nice day! :)

X + 4y = -9 . . . (1)
2x + 5y = -6 . . . (2)
From (1): x = -9 - 4y . . . (3)
Substituting (3) into (2) gives, 2(-9 - 4y) + 5y = -6
-18 - 8y + 5y = -6
Required equation is -18 - 3y = -6
