Can you solve this using elimination method. Thanks. And can you give it a step by step explanation so i can understand. :D
y=2x-1
2x=3y+2
y=2x+3
y=x-1
3x+y=1
-3x+2y=1
x-5y=1
2x-3y=5
4x-3y=2
3x-4y=4

Answer:
HELLO MATE.....A VERY GOOD MORNING TO YOU...
1).
y = 2x - 1. 》》- 2x + y = -1 --------->eq. 1
2x = 3y + 2. 》》2x - 3y = 2 --------->eq. 2
adding eq. 1 and eq. 2,
- 2x + y = - 1
2x - 3y = 2
-----------------
0 - 2y = 1
》 y = - 1/2
and x....
subs. y in in eq. 2..
2x = -3/2 + 2
2x = 1/2
》x = 1...
-----------------------------------------------
2).
y = 2x + 3.......eq. 1
y = x - 1...........eq. 2
subtracting eq. 2 from eq. 1....
》》x = 4
therefore y = 3.....
------------------------------------------------
3).
3x + y = 1.....eq. 1
-3x + 2y = 1..eq. 2
add 1 and 2
》 3y = 2
》 y = 2/3
and...
》 x = 1/9
--------------------------------------------------
4).
x - 5y = 1......eq. 1
2x - 3y = 5...eq. 2
multiply 1 by 2 and subtract 2 from 1
-7y = - 3
y = 3/7
x = 26/14
--------------------------------------------------
5).
4x - 3y = 2.......eq. 1
3x - 4y =4........eq. 2
multiply eq. 1 by 3 and eq. 2 by 4 and subtract the results..
y = 0
x = 1/2
---------------------------------------------------
HAVE A NICE DAY...
HOPE IT HELPS YOU..
PLS MARK AS BRAINLIEST ✌✌✌
