Answer:
one comic book costs $5
Step-by-step explanation:
let cost of comic book = $x
let cost of vinyl = $y
according to the question:
6x = y + 3x
y = 6x - 3x
y = 3x (1)
y = $15 (2)
substituting the value of y from equation (2) into equation (1)
15 = 3x
x = 15/3 = 5
thus, cost of one comic book = $5
Answer:
5$.
Step-by-step explanation:
Let's denote the cost of one Sailor Moon comic book as x .
The cost of 6 Sailor Moon comic books is 6x.
According to the given information, the cost of a Nirvana vinyl plus 3 comic books is equal to the cost of 6 Sailor Moon comic books.
So, 15 + 3x = 6x , as the vinyl costs $15.
Now, let's solve for x :
Subtract 3x from both sides: 15 = 3x
Divide by 3: x = 5
Therefore, the cost of one Sailor Moon comic book is $5.
2x-y=0
*x=-1,y=-2
*x=1,y=2
*x=2,y=1
*x=-2,y=-1
Answer:
Solving this system of linear equations by elimination we get x=-1 and y=-2
Option 1 is correct option.
Step-by-step explanation:
We are given equations:
We need to solve by Elimination method.
Elimination method: Add or subtract the equations to get an equation in one variable.
Rearranging the equation 1 we get
Add eq(1) and eq(2)
So, after eliminating y we get x=-1
Now finding y by putting x in eq(1)
We get y=-2
So, solving this system of linear equations by elimination we get x=-1 and y=-2
Option 1 is correct option.
