DARE CORONA AO QUE ME RESPONDA CORRECTO ME URGE​

Answer 1

Explicación paso a paso:

4x+6y=24

4x=24-6y

x=24-6y/4

2x-4y=8

2x=8+4y

x=8+4y/2

24-6y/4=8+4y/2

2*(24-6y)=(8+4y)4

48-12y=32+16y

48-32=16y+12y

4=28y

y=4/28=2/17=1/7

y=1/7

2x-4y=8

2x-4*1/7=8

2x-4/7=8

2x=8+4/7

2x=56/7+4/7=60/7

x=60/7/2=

60/7/2/1=

=60/14

2*60/14-4*1/7

120/14-4/7=

120/14-8/14=

112/14=8✓
