Question

4x - y = 14
5x + 2y =11}
igualación alguien??

Answer 1

Respuesta:

x= 3. y= - 2

Explicación paso a paso:

4x - y - 14 = 5x + 2y - 11

-y -2y =5x - 4x - 11 + 14

-3y = 1x +3

x = -3y -3

(x +3)/-3 = y

4x - (x+3)/-3 =14

4x +x/3 + 3/3 = 14

4x + x/3 +1 =14

13x/3=14-1

13x/3 = 13

x/3 = 13/13

x/3 = 1

x= 3

5x + 2 y = 11

5(3) + 2y = 11

15 + 2y = 11

2y = 11 - 15

2y = - 4

y= -4/2

y= -2
