Question

solucion de sistemas de ecuacion de 2x2 metodo grafico


5y + 2x = 3

3y - 4x = 1

Answer 1

5y + 2x = 3

3y - 4x = 1

10y + 4x = 6

3y - 4x =  1

10y +4x +3y -4x =6+1

13y = 7

y = 7/13

5(7/13) + 2x =3

35/13 + 2x = 3

2x = 3 - 35/13

2x = 39/13 - 35/13

2x = 4/13

x = 4/13 ÷ 2

x = 4/13 ÷ 2/1

x = 4/13 x 1/2 = 4/26

x = 2/13

Respuesta final

x = 2/13

y= 7/13
