Answer:

10

Step-by-step explanation:

5y + 2y -4y = 30

To solve first combine like terms

5y+2y-4y=3y

Then isolate your variable, do this by dividing both sides by 3.

3y=30

3y/3=30/3

Finally, simplify

y=10

16. Find the value of y. ​
devlian [24]

y + (2x -12) = 180 (since they are supplementary angles)

(2x-12) = 96 ( since they are alternate exterior angle)

2x = 96 + 12

2x = 108

x = 108/2

x = 54.

y+( 2x-12)=180

y+(2× 54 -12) = 180

y + (108-12) = 180

y + 96 = 180

y= 180-96

y = 84.
