Answer:

Step-by-step explanation:

Khan gives you right answer and tells you what's wrong, but this site is for help so, all you need to do is use the destructive property.

12 x 2= 24 12 x 3 = 36 12 x -1 = -12

now you have the original expression, 24 + 36 - 12 (without the letters.)

Answer:

x = 0

y= -3

Step-by-step explanation:

x = y + 3 into the equation y = -4x - 3, so

y = -4(y+3) - 3

y = -4y - 12 - 3

y = -4y - 15

5y = -15

y = -3

Then, you can substitute this into the equation x = y + 3

$x = -3 + 3\\x = 0$
