I assume you are trying to solve for each variable. if thats the case you want to use one equation to solve for y and then plug the y value into the next variable
Problem: y =-3x=4 so -3x+4=3x-2
x=1
plug x value into one of the equations
y=3(1)-2
y=1
Answer: 76/8547
Step-by-step explanation:
two possibilities
3 boys or 4 boys it would end up as
(18C3+18C4)/37C5
Answer:

Step-by-step explanation:
Money to be spent is not more than $400.
Cost of a case of water = $7
Cost of each sandwich = $5
Let number of cases of water bought be 
Number of sandwiches bought be 
From the question we get

The inequality which would determine how many sandwiches, and how many cases of water that can be bought is
.
I'm assuming they just want you to simplify the expression:
1/2 × 6 + 11
3 + 11
14
Answer:
Step-by-step explanation:
i think that the equations might be y = x - 7
