Question

x = y + 1
4x + 2y = 22

Answer 1

Respuesta:

x= 4

y= 3

Explicación paso a paso:

x = y + 1

4x + 2y = 22

4x= 22-2y

x= 22-2y/4

y+1 = 22-2y/4

4( y+1) = 22-2y

4y +4= 22-2y

4y +2y = 22-4

6y= 18

y=18/6

y= 3

4x+2y =22

4x+2(3)= 22

4x+6= 22

4x= 22-6

4x= 16

x= 16/4

x= 4

Comprobación

x = y + 1

4= 3+1

4=4

4x + 2y = 22

4( 4) + 2 ( 3) = 22

16 + 6 = 22

22= 22
