Вопрос:

-3y+10x-0,1=0, 15x+4y=2,7

Ответ:

From the first equation, 3y = 10x - 0.1, so y = (10x - 0.1)/3.
Substitute into the second equation: 15x + 4((10x - 0.1)/3) = 2.7
45x + 40x - 0.4 = 8.1
85x = 8.5
x = 0.1
Substitute x back into the equation for y: y = (10(0.1) - 0.1)/3 = (1 - 0.1)/3 = 0.9/3 = 0.3
Answer: x = 0.1, y = 0.3
