Question

5x + 2y = 13 ; 4x -3y = 15​

Answer 1

Answer:

x= 3 and y= -1

Step-by-step explanation:

5x+2y = 13 --------- (1)

4x-3y = 15 ----------(2)

by solving (1) and (2)

(1)×3 » 15x+ 6y = 39

(2)×2» 8x- 6y = 30

__________________

(1)+(2) » 23x = 69

x= 3

put x= 3 in equation (1)

5(3)+ 2y = 13

2y = 13-15

2y = -2

y = - 1
