Question

0.4x+0.3y=1.7;0.7x-0.2y=0.8​

Answer 1

Answer:

X is 2 and y is 3

Step-by-step explanation:

Multiplying first and second equation by 10,

4x+3y=17, 7x-2y=8

Multiplying first equation by 2 and second by 3,

8x+6y=34 - - - (1), 21x-6y = 24----(2)

(1)+(2):

29x=58

X=2

8(2)+6y=34

6y=34-16

6y=18

y=3
