First we, Subtract the 16 from 2x ( which we can't do) so we change the equation to 16 - 2x = 4y
Second we, solve for x. x = −2y + 8, We divide both sides by 2,
-2y/-2= y ( The two -2s cancle each other ) 8/2= 4
x = 4
Next we, solve for y. y = 4 −x/2y, we multiply both sides by 2y,
4 * 2y = 8y ( LOL ) -x/2y * 2y = -x
NOW WE have 8y - x
IDK anything beyond this I'm SORRY T.T
But for the coordinates x is 4
