A fraction like 8/8 or 3/3 would equal one whole.
5x - 3y = 9
5x = 9 + 3y
5x - 9 = 3y
( 5x - 9 ) / 3 = y
y = ( 5 / 3x ) - ( 9 / 3 ) ( I just split the common denominator to individual parts )
y = 5 / 3x - 3
(4w-6)+w+w=180
4w-6+2w=180
6w-6=180
6w=186
w=31
4w-6=4(31)-6=124-6=118
The value of w is 31. Angle P is 118 degrees.
What do you need to figure out. i am happy to help
