Question

3x+2y=8
4x-3y=8 Método de Sustitución

Answer 1

Explicación paso a paso:

3x+2y= 8

4x-3y= 8

Metodo de sustitucion

3x+2y=8

3x= 8-2y

x=(8 -2y)/3

4x-3y=8

4(8-2y)/3 -3y = 8

4(8-2y) - 9y = 24

32-8y -9y=24

32-24= 17y

8=17y

8/17=y

x=[ 8-2(8/17)]/3

x= (8-16/17)/3

x= (120/17)/3

x=40/17
