Question

solve by cross multiplication 3x - 2y = 8 and 4x + 3y = 5​

Answer 1

Answer:

x=2

y= -1

Step-by-step explanation:

(3x-2y=8 )*3

9x-6y=24  eq number 1

(4x+3y=5) *2

8x+ 6y=10  eq number 2

add equation 1 and 2

9x-6y+8x+6y=34

9x+8x=34

17x=34

x=2

substitute x=2 to equation 1

9x-6y=24

18-6y=24

y= -1
