Answer:
y = 2/3
Step-by-step explanation:
Assuming you are looking for "y":
15 * ( y - 4 ) - 2 * (y - 9 ) + 5 * (y + 6) = 0
15y - 60 - 2y + 18 + 5y + 30 = 0
15y - 2y + 5y -60 + 18 + 30 = 0
18y = 60 - 18 - 30
18y = 12
y = 12/18
y = 2/3
Two lines intersecting at a right angle would be perpendicular. Parallel lines do not cross or touch each other, and rats don’t form right angles. Perpendicular lines are horizontal and vertical crossing together to form a right angle.

1) use distributive property
3x - 6 + 5x + 4
8x - 2
2) 4-2x - 14 - 3
-14 - 2x
47/100 and 47.00 are what I can think of.
