Question

3y + 12 = 7y 5x + 7 = 3x + 5 2( x + 14) = 200 x/2 = 300 no entiendo eso xd

Answer 1

Respuesta:

y=1/2; x=-1 ; x=86 ; x=150

Explicación paso a paso:

3y+2=7y

2=7y-3y

2=4y

2/4=y

1/2=y

-----------------

5x+7=3x+5

5x-3x=5-7

2x=-2

x=-2/2

x=-1

-----------------

2(x+14)=200

x+14=200/2

x+14=100

x=100-14

x=86

-----------------

x/2=300

x=300/2

x=150
