Question

0.2x+0.3y=1.3. 0.4+0.5y=2.3by elimination method​

Answer 1

Answer:

x = 2, y = 3.

Step-by-step explanation:

0.2x + 0.3y = 1.3

0.4x + 0.5y = 2.3

x + 1.5y = 6.5

1.2x + 1.5y = 6.9

0.2x = 0.4

x = 2.

1.2(2) + 1.5y = 6.9

2.4 + 1.5y = 6.9

1.5y = 4.5

y = 3.

Answer 2

Answer:

y=3 and x=2

Step-by-step explanation:

0.2x+0.3y=1.3 * 10 0.4x+0.5y=2.3 *10

2x+3y=13 *2 4x+5y=23

4x+6y=26

4x+6y=26

4x+5y=23

----------------------

y=3

=> 4x+5y=23

4x +5(3) =23

4x=23-15

x = 8/4

x=2
