Question

3x-
4y - 7 , 5x +2y=3​

Answer 1

Answer:

x = 1 , y = - 1

Step-by-step explanation:

3x - 4y  = 7 ------ ( 1 ) × 1

5x + 2y = 3 ------ ( 2 ) × 2

___________________

3x -  4y  = 7 ----- ( 3 )             ( add the two equations )

10x + 4y = 6 -----( 4 )            

_______________

13x = 13  

x = 13/13

x = 1

use x = 1 in equation ( 1 ) :

3x - 4y = 7

3 ( 1 ) - 4y = 7

3 - 4y = 7

- 4y = 7 - 3

- 4y = 4

y =  - 4/4

y = - 1

hope it helps have a wonderful day
