Question

система уравнений

4x+17y=-35
6x+13y=-15

Answer 1

4x+17y=-35

6x+13y=-15

4x+17y=-35

x=-5/2-13/6 y

4×(-5/2-13/6 y)+17y=-35

y=-3

x=4

Answer 2

а можно развернуто, если не сложно?

Answer 3

$left { {{4x+17y=-35}|*6 atop {6x+13y=-15}|*4} right. left { {{24x+102y=-210} atop {24x+52y=-60}} right. |-\24x-24x+102y-52y=-210-(-60)\50y=-150\y=-3\4x+17*(-3)=-35\4x=-35+51\4x=16\x=4\left { {{y=-3} atop {x=4}} right.$
