Question

Metodo de igualacion
4x+3y=11
5x-2y=8

Se los ruego ayudenme, si contestan bien doy coronit

Answer 1

4x + 3y = 11

5x - 2y = 8

x1 = 11 - 3y/4

x2 = 8 + 2y/5

11 - 3y 8 + 2y

_____ = ______

4 5

5 (11 - 3y) = 4 (8 + 2y)

55 - 15y = 32 + 8y

-15y - 8y = 32 - 55

(-) -23y = -23

y = 23/23

y = 1

4x + 3y = 11

4x + 3(1) = 11

4x + 3 = 11

4x = 11 - 3

4x = 8

x = 8/4

x = 2

5x - 2y = 8

5x - 2(1) = 8

5x - 2 = 8

5x = 8 + 2

5x = 10

x = 10/5

x = 2

x = 2 ; y = 1

Comprobación

4x + 3y = 11

4(2) + 3(1) = 11

8 + 3 = 11

11 = 11

5x - 2y = 8

5(2) - 2(1) = 8

10 - 2 = 8

8 = 8

Espero haberte ayudado. Suerte en los estudios ≧◠◡◠≦.
