You would do 150/15=10 since this is a percent change it to a decimal(.10) to check do 150x.10=15 and 15/.10=150
You can use the quadratic formula with it which will be easier
or simple factoring
it will be (5x-11)(7x+4)

Answer:
x = 14
Step-by-step explanation:
The sum of angles in a triangle is 180°:
∠O +∠P +∠Q = 180°
(2x -5)° +(3x -8)° +(10x -17)° = 180°
15x -30 = 180 . . . . . divide by °, collect terms
x -2 = 12 . . . . . . . . . divide by 15
x = 14 . . . . . . . . . . . .add 2
