19x+12y=17
step 1: move the thing that you're looking for to the left side and all the rest to the right side:
(19x +12y)-19x = 17 -19x
12y = 17 -19x
step 2: to find y, you need to get rid of 12. to do so you need to devide everything by that number:
(12y)/12 = 17/12 -19/12 x
y= 17/12 -19/12 x
step 3: simplify of possible. ( in this exercise it isnt)
step 4: rearange the equation if necessary
y= 17/12 + -19/12x
y= -19/12x + 17/12

Answer:
0.2
Step-by-step explanation:
We have,
Number of blue tiles = 2
Number of red tiles = 3
Number of yellow tiles = 5
Total number of tiles = 2 + 3 + 5 is 10
Now, the probability of picking a blue tile is:
The number of blue tiles divided by the total number of tiles:
2 ÷ 10 = 0.2
