Answer:
I believe 1.) is x=y-4/2 and 2.) x=y-4/2 as well
Step-by-step explanation:
1.)
y=2x+4
-subtract 4 on both sides-
y-4=2x
-divide 2 on both sides-
x=y-4/2
2.)
y=2(x+2)
-distribute the 2-
y=2x+2
-subtract 2 on both sides-
y-2=2x
-divide 2 on both sides-
x=y-2/4
I dont know exactly if this is correct, but i hope it helps! :)
Given:-
To find:-
Wheather the given sides form a valid triangle.
So now let,
To check we use the condition,
Substituting the values we get,
In the above condition 12+7>20 is wrong.
So the condition fails and the given sides doesnt form a triangle.
