Answer:
and 
Step-by-step explanation:
- To use the substitution method, we should take one of the equations, and obtain an expression for one of the variables from this equation. Let's take the first one: 3x-2y = 11. We obtain an expression for x (it could be for y as well): 3x = 11 + 2 y ⇒
. - Now, we should replace the expression obtain for x in the first equation, on the second equation, as follow
⇒ 
- Then rearranging terms

- This expression results in

- Finally, using the firs equation, in which we obtained an expression from x,
, we replace y=1/2 and get
, then 
Answer:
You cannot solve for x on any of these. it will just be the same answer.
Step-by-step explanation:
90 because there are 5 time as many candies with nuts as candies without nuts and there is 18 so it will be 18×5=90
Answer:
40+6x
Step-by-step explanation:
11+11+9+9=40 x*x*x*x=x 3x+3x =6x bring the 6x down and it will be 6x+40
