<span>Hence
2L + C = 1.4
-2L - 6C = -3.4
Add (This will eliminate 'L' )
-5C = -2.0
5C = 2.0
C = 0.4 = £0.40p
2L + 0.4 = 1.40
2L = 1.40 - 0.40 = 1.00
L = 0.50 = £0.50p.
Hence a lemonade (L) costs £0.50p & a Crisps (C) costs £0.40p.</span>
First off, you need to have your ys on the same side. Here's how to do it:
4y + 15 = -5y + 9
4y + 5y = 9 - 15 (once a number goes to the other side, it changes its sign)
9y = -6
y = -6/9
y = -2/3
The correct answer is B. -2/3

Step-by-step explanation:
If I started at the y point and follow the graph line. Then you will see that I will be going down the graph.
Hope this helped
B. y=x+2x-2 is the correct quadratic function
