Step-by-step explanation:
x = -3 -y
2(-3 -y) =0
-6 -2y = 0
-2y = 6
y = -3
= -3 -(-3)
= -3+3 = 0
7. q+18 =22
q+18-18 =22-18 , q=4
at the problem q+18-18=22+18 mistake (should be subtracted from both sides)
8. r+10-10=22-10 r=12
r-15+15=5+15 r=20
r-18+18=14 +18 r=32
r+5-5=15-5 r=10
Answer:
1) y = 41
2) y = 4

Answer:
x = 7
Step-by-step explanation:
Suppose ray UW divides ∠TUV into two angles ∠ TUW and ∠ WUV.
Then, m∠TUV = m∠ TUW + m ∠ WUV
Given m∠TUV = (9x + 1), m∠ TUW = (7x - 9) and m ∠ WUV = (5x - 11)
Substitute these values in (i) we get
9x + 1 = 7x - 9 + 5x - 11
9x + 1 = 7x + 5x - 9 - 11
9x + 1 = 12x - 20
12x - 9x = 1 + 20
3x = 21
x = 21/3
x = 7
