i hope this will help u...
plz mark as brainlist....☺️☺️☺️
Answer:
Step-by-step explanation:
23u - 29v = 98 ........equation 1
29u - 23v = 110 ........equation 2
23u - 29v = 98 (x29)
29u - 23v = 110 ( x23)
667u - 841v = 2842 .........equation 3
667u - 529v = 2530 .........equation 4
(sutracting equation 4 from 3)
667u - 841v = 2842
667u - 529v = 2530
- + - (changing the signs)
0u -312v = 312
now, from above
-312v = 312
v = 312/-312
v = -1
substiuting the value of v in equation 1
= 23u - 29v = 98
= 23u - 29(-1) = 98
= 23u + 29 = 98
= 23u = 98-29
= u = 69/23
= u = 3
Ans : v = -1
u = 3
Hope it helps....
