2x-4y=8
Add 4y to each side to separate the variables, since you want to solve for x let be on the left
2x=4y+8
Divide the entire equation by 2 to allow x to stand alone
x=2y+4
And I have to type some more so it will let me answer the question so here ya go

They can be arranged in 48 ways.
The little square in the top left corner means it is a right angle which equals 90 degrees.
The bottom angle is given as 56.7 degrees.
The three inside angles of a triangle need to equal 180 degrees.
The missing angle = 180 - 90 - 56.7 = 33.3 degrees
