The given equation is ⇒⇒⇒ 2y - 4x = 6
∴ 2y = 4x + 6 ⇒ divide all the equation over 2
∴ y = 2x + 3 and it can be written as ⇒⇒⇒ y - 2x = 3
The last equation represents a straight line with a slope = 2 and y-intercept = 3
To construct a system of equations with definitely many solutions and the equation ( 2y-4x=6 ) is one of the equations, the other equation must have the same slope and the same y-intercept.
so, the general solution of the other equation is ⇒ a ( y - 2x ) = 3a
Where a is constant and belongs to R ( All real numbers )
The system of equations which has definitely many solutions is consisting of <u>Coincident lines.</u>

Step-by-step explanation:
Answer:
The required equation is c = 1.59 - s
Step-by-step explanation:
Here, s represents the sales price per pack and c represents the cost saving,
Also, the regular price per pack = $ 1.59,
Since,
Cost saving = Regular price - sales price
⇒ c = 1.59 - s
Which is the required equation that is used to determine how much money is saved if the pack is bought today.
