Answer:
Step-by-step explanation:
Let x represent the number of toys that each club member donated.
There are 9 students in a service club. 
If each club member donated 4 children's books for the baskets, it means that the total number of books donated by the club members would be 
9 × 4 = 36
If each club member also donated an equal number of toys. It means that the total number of toys donated by the club members would be 
9 × x = 9x
A total of 63 items were collected for the baskets. Therefore, the linear equation that you can use to find how many toys each club member donated would be 
9x + 36 = 63
 
        
             
        
        
        
Get x on one side then you can use substitution
So, change x+3y=3 to x= -3y+3
Then plug in x to other equation to find y
2(-3y +3)-3y=-12
-6y + 6 -3y = -12
-9y = -18
Divide both sides by negative nine to find y
y = 2
Then plug in to original equation to find x
x + 3(2) = 3
x + 6 = 3
x = -3
So, y = 2 and x = -3
        
                    
             
        
        
        
Answer:
Let the number of hours traveled by train be "x".
The x = the number of hours traveled by plane.
-------------------------------------------------
Equation:
train distance + plane distance = 1300 miles
50x + 275x = 1300
x(325) = 1300
x = 4 hours
