Question

2(x+1) /3 - y = 3

3(x+5-y) + 3x= 12

​

Answer 1

Respuesta:

●2(x+1)÷3-y=3

2x+2÷3-y=3

2x+2-3y=9

2x-3y-(-3y)=9-2-(-3y)

2x=9-2-(-3y)

2x=3y+7

x=3y+7/2

x=(3y+7)x1/2

x=3/2y+7x1/2

x=3/2y+7/2

●3(x+5-y)+3x=12

6x+15-3y=12

6x-15-(-3y)=12-15-(-3y)

6x=12-15-(-3y)

6x=3y-3

x=(3y-3)÷6

x=(3y-3)×1/6

x=1/2y-3×1/6

x=1/2y-1/2
