Answer 1

Respuesta:

4{6x - 5y = 8

5{2x + 4y =14b

24x - 20y = 32

10x + 20y = 70b

34x = 32 + 70b

x = 32 + 70b/34

2x + 4y = 14b

2(32 + 70b/34) + 4y = 70b

64 + 140b/34 + 4y = 70b

4y = 70b - (64 + 140b/34)

4y = 2380b - 64 - 140b/34

4y = 2240b - 64/34

y = 2240b -64/34/4

y = 4(2240 - 64)/34
