Question

6×-18y=24 -3×+9y=-12

Answer 1

Resposta:

Let's solve for x.

6x−18y=24

6x−18y+18y=24+18y

6x=18y+24

6x/6=18y+24/6

Answer:

x=3y+4

Let's solve for y.

6x−18y=24

6x−18y+−6x=24+−6x

−18y=−6x+24

−18y/−18=−6x+24/−18

Let's solve for x.

−3x+9y=−12

−3x+9y+−9y=−12+−9y

−3x=−9y−12

−3x/−3=−9y−12/−3

Answer:

x=3y+4

Let's solve for y.

−3x+9y=−12

−3x+9y+3x=−12+3x

9y=3x−12

9y/9=3x−12/9

Answer:

y=⅓ x+ −4/3

Answer 2

Resposta:

Explicação passo a passo:

6× - 18y = 24

-3× + 9y = -12

x = 1     y = - 1

6.1 - 18. -1 =                    - 3 . 1 + 9 . - 1 =

6 + 18 = 24                      - 3 - 9 = - 12
