Question

f)

(4X + 2Y = 10
5X +3Y = 13. Igualacion

Answer 1

Respuesta:

x = 2 ; y = 1

Explicación paso a paso:

4X + 2Y = 10

x = -2y + 10 / 4

5X +3Y = 13

x = -3y + 13 / 5

5 ( -2y + 10) = 4( -3y + 13)

-10y + 50 = -12y + 52

-10y + 12y = 52 - 50

2y = 2

y = 2/2

y = 1

reemplazamos para obtener x

4X + 2Y = 10

4x + 2*1 = 10

4x + 2 = 10

4x = 10 - 2

4x = 8

x = 8/4

x = 2

comprobación

4X + 2Y = 10

4 * 2 + 2 * 1 = 10

8 + 2 = 10

10 = 10 ✅✅

5X +3Y = 13

5 * 2 + 3 * 1 = 13

10 + 3 = 13

13 = 13 ✅✅
