Question

Помогите с алгеброй буду очень благодарен

Answer 1

1) $left { {{x-3y=8} atop {2x-y=6}} right. = left { {{x=8+3y} atop {2(8+3y)-y=6}} right.$

2(8+3y) - y=6
16+6y-y=6
5y= -10
y = -2

x = 8 + 3*(-2) = 8-6=2

2) $+ left { {{4x-5y=-83} atop {2x+5y=29}} right. = 6x=-54$
x = -9

2*(-9) +5y = 29
-18+5y=29
5y = 47
y = 9.4

Answer 2

А можно 5
