Answer 1

Answer:

I hope this answer help you

Answer 2

Answer:

x = 2, y = 3

Step-by-step explanation:

We will solve the equations by elimination method.

0.2x + 0.3y = 1.3                     ----------- 1

0.4x + 0.5y = 2.3                    ----------- 2

Multiplying equation 1 by 2.

0.4x + 0.6y = 2.6                    ----------- 3

Subtracting equation 3 from 2.

-0.1y = -0.3

y = 3

Substituting value of y in equation 1.

0.2x + 0.9 = 1.3

0.2x = 0.4

x = 2
