Question

2x+5y=17
3x4y=15
metodo de reducion

Answer 1

Respuesta:

y= 3, x= 1

Explicación paso a paso:

2x + 5y = 17 .....3 2x + 5(3) = 17

3x + 4y = 15 ....2 2x = 17 - 15

------------------ 2x = 2

6x + 15y = 51 x = 1

-6× - 8y = -30

---------------------- 3x + 4y = 15

7y = 21

y = 3 3(1) + 4(3) = 15

3 + 12 = 15

2x +5y = 17 15 = 15

2(1) +5(3) = 17

2 + 15 = 17

17 = 17
