Sin75° = Sin(30° + 45°)
= Sin30°.Cos45° + Sin45°.Cos30°
= 1/2 . √2/2 + √2/2.√3/2
= √2/2 ( 1/2 + √3/2 )
= √2/2 ((1+√3 ) /2 )
= (√2 + √6 )/ 4

Esay, first what you have to do us move -6 to the right side and now you will have 3y=-3x+6, what you want to do next is to divide 3y by both sides and your final answer is y=-x+2, hope this helps.
Answer: -3x+2y=16 equals y = 3/2x+8
2x+y=1 equals y= -2x+1
