Answer:
B. 2x + y = 4
Step-by-step explanation:
If you look carefully, you will see that
y = -2x + 4 and
2x + y =4
are the same equation, so there are infinitely many solutions for the system, namely, all the points on the line y = -2x + 4
If you want to find an example of solution, just give arbitrary values to x and solve for y.
For example
x = 1, y=2 is one solution
x=2, y = 0 is another one.
There are as many solutions as values of x you try, so there are infinitely many.

Answer:
Step-by-step explanation:
sum of interior angles in a triangle is 180 degree
interior angles are (5x+3y)∘,(3x+20)∘, and (10y+30)
add all the angles and make it equal to 180
combine like terms
subtract 50 from both sides
