X+y = 2
(2*2 + 2*2)
(4 + 2*2)
(4 + 4)
= 8
Answer:
it should be 42 hope it helps
Step-by-step explanation:
Al I know is that you have to use systems of equations to solve it. Sorry
A: 2/1 -> 2
B: -1/1 -> -1
Gradient or slope is the change in the y value/change in the x value
Y value is up and down and x value is side to side.
Hope this helps! :)
