Answer:
41
Step-by-step explanation:
These angles are vertical angles, and vertical angles are equal
2x+1 = 7x-99
Subtract 2x from each side
2x+1-2x = 7x-2x-99
1 = 5x-99
Add 99 to each side
1+99 = 5x-99+99
100 = 5x
Divide each side by
100/5 = 5x/5
20 =x
The 2x+1 angle equals
2(20)+1
40+1

On the y-axis. Right in the middle of 12 and 13.
10xy+2y+8x+7
Explanation
3xy + 4xy + 3xy = 10xy
The others cant be simplified so
10xy + 2y + 8x + 7
