Answer:
Therefore the value of 'y' is,

Step-by-step explanation:
Given:

To Find:
y= ?
Solution:
........Given
Step 1. Adding 50 to both the side we get

Step 2. Dividing by 10 on both the side we get

Therefore the value of 'y' is,

Answer: y = 5 + 
Step-by-step explanation:
-4y + 2x = -20
Move the variable to the right
-4y = -20 - 2x
Divide Both sides
5 +

Answer:
3
Step-by-step explanation:
D(1 , 1) to D'(3, 3)
so x (1 x 3)= 3
y (1 x 3) = 3
SF = 3
D(1 , 5) to D'(3, 15)
so x (1 x 3)= 3
y (5 x 3 ) = 15
SF = 3
Same on coordinate points B to B' and C to C'
so SF = 3
