Question

reduccion 3x+5y=5 -3x+ 7y=36​

Answer 1

Respuesta:

3x+5y=5 x = 5+5y

-3x+7y=36 -x =36+7y

1) 5+5y = -36+7y

5y - 7y = 5 - 36

y = 31 / 2

y = 15.5

2) x = 5+5y

x = 5+5(15.5)

x = 5+20.5

x = 25.5

1. x = 25.5 | 2. y = 15.5

1. x - 5y = 5 | 2. -x - 7y = 36

1. (25.5)-5y(15.5)= 77.5 | 2. (25.5)-7 (15.5)=108.5

1. 25.5 - 77.5 = 52 | 2. 25.5 - 108.5 = -83

1. 52 = 52 | 2. -83 = - 83
