Not sure if I got the equations right but this is how I solved it:
Rearrange 6x-y=4 for y. Then since both equations equal y, you can set them equal to each other. From there solve for the y variable. To solve for x, plug in the new found y variable back into one of the original equations. Hope that helps
It will either have infinite solutions or no solutions.
If the lines are parallel, they will have no solutions.
If the lines are on top of each other, they will have infinite solutions.
So the answer is false.
Answer
Find out the ratio represented the number of yellow balls to red balls .
To proof
Let us assume that the number of yellow balls be x.
As given
There are 20 balls in a bag.
Ten of the balls are red, 4 are green, and the rest are yellow.
than the equation becomes
x + 10 + 4 = 20
x = 20 - 14
x = 6
therefore the number of yellow balls be 6 .
Now find out the ratio between the the number of yellow balls to red balls .
the number of yellow balls be 6 .
the number of red balls be 10 .
solving
Therefore the ratio of the the number of yellow balls to red balls is 3 :5 .
Option (d) is correct .
Hence proved
Im gonna have to say its c
