For this case we can propose an equation that will allow us to find the price of one of the books knowing the price of the other.
x: Let the variable that represents the price of the book with a green sticker
y: Let the variable that represents the price of the book with a yellow sticker
According to the statement we have:


Finally, we can substitute the price of one of the books and clear the value of the other as the case may be.
Answer:

Answer:

Step-by-step explanation:
So we have the equation:

First, subtract 3 from both sides:

Definition of absolute value:

Divide both sides by 6 for both equations:

And we're done!
Let the number of pants have to be made be x.
So,
9.55 * x = 525.00
x =

≈ 54.97
Thus, the number of pants have to be made are 54.
This question is worded slightly strangely but I believe I understand it.
To eliminate x, multiply the second equation by 8, so that it becomes 4x + .8y= 96
Then you can subtract 4x on the top by 4x on the bottom to eliminate it.
the equation of the line is y = 3x - 5
