Answer:
2 ; 10
Step-by-step explanation:
a + B = 12
a - B = 8

B = 2
A = 10
Answer:
Step-by-step explanation:
1. 2x - 9y = 23
2 x = 9 y + 23
y = (2 x)/9 - 23/9
2 x - 9 y - 23 = 0
2. 5x - 3y = -1
5 x + 1 = 3 y
y = (5 x)/3 + 1/3
5 x - 3 y + 1 = 0
I belive that should help you out a bit :D
The answer is 122/495. Hope this helps!
