Answer 1

x=1 y=2

$0.5x - 0.3y = - 0.1 \\ 1.2x + 0.1y = 1.4 \\ \\ 0.5x - 0.3y = - 0.1 \\ 1.2x \times 3 + 0.1y \times 3 = 1.4 \times 3 \\ \\ 0.5x - 0.3y = - 0.1 \\ 3.6x + 0.3y = 4.2 \\ \\ 3.6x + 0.5x = 4.2 - 0.1 \\ 4.1x = 4.1 \\ x = 1 \\ \\ 0.5 \times 1 - 0.3y = - 0.1 \\ 0.5 - 0.3 y= - 0.1 \\ 0.3y = 0.5 + 0.1 \\ 0.3y = 0.6 \\ y = 0.6 \div 0.3 = 2$

x=1,y=2
