Answer:
[tex]x = - 1 \\ - 2 + 0.4y = 0.4 \\ 0.4y = 0.4 + 2 = 2.4 \\ y = 2.4 \div 0.4 = 6 \\ y = 1 \\ 2x + 0.4 = 0.4 \\ 2x = 0.4 - 0.4 = 0 \\ x = 0[/tex]
[tex]2x + 0.4y = 0.4 \\ 2( - 1) + 0.4y = 0.4 \\ 0.4 y = 2.4 \\ y = \frac{2.4}{0.6} \\ \therefore \: y = 6 \\ 2x + 0.4(1) = 0.4 \\ \therefore \: x = 0[/tex]
