Step-by-step explanation:

So, our solution is (x, y) = (3, 2)

Step-by-step explanation:

Given that

1.5x + 0.1y = 6.2 ......(1

3x - 0.4y = 11.2 .......(2

Multiplying equation (1) by 2 on both sides, we get

3x + 0.2y = 12.4 .....(3

From equation (2)

3x = 11.2 + 0.4y .....(4

Now, substitute the value of 3x from equation (4) into equation (3)

11.2 + 0.4y + 0.2y = 12.4

0.6y = 12.4 - 11.2

0.6y = 1.2

y = 1.2÷0.6

y = 2

Now, substitute the value of y into equation (4)

3x = 11.2 + 0.4 (2)

3x = 11.2 + 0.8

3x = 12

x = 12÷3

x = 4

So, our solution is (x, y) = (3, 2)
