Answer:
Solution (-2, 7)
Step-by-step explanation:
2x + 3y = 17 (1)
5x + 6y = 32 (2)
Using elimination method
Multiply (-2) to the equation (1)
-4x - 6y = -34
Now you have 2 new equations
-4x - 6y = -34
5x + 6y = 32
----------------------------Add
x = -2
Substitute x = -2 into 2x + 3y = 17
2(-2) + 3y = 17
- 4 + 3y = 17
3y = 21
y = 7
Solution (-2, 7)

Answer:
3.627 = d
Step-by-step explanation:
C = 11.4mm
d = ?
C = πd
11.4 = 22/7 × d
cross multiply
11.4 ×7 = 22d
79.8 = 22d
Divide both sides of the equation b 22
79.8/22 = 22d/22
3.627 = d
