Answer:
The solution is x = -2, y = -3
Step-by-step explanation:
Let's start with the equation 3x + y = -9
Substitute the y for 5x+7 seen in the second equation
Now you have 3x + (5x+7) = -9
Lets solve:
Let's add the x's
Now we have 8x + 7 = -9
Substracy seven from each side
Now we have 8x = -16
Now let's divide 8 on each side
Now we have x = -2
Now lets plug in -2 to the second equation
The second equation is y = 5x+7
When we plug in -2 we get y=5(-2)+7
We multiply
We now have y = -10+7
Add
y = -3
The solution is x = -2, y = -3
Answer:
x>20
Step-by-step explanation:
subtract 5 from both sides
Answer:
I belive it is 105
Step-by-step explanation:
ok so by spliting this up into where the 9 lengh ends.that recctangle is now 9 by 6,to find area you multiply them,that gets you 54.Now for the other part you want to fill it in,when you do that the area is 6 by 11 what equals 66 but ou have to take away the corner making it 51.Now we add those together and you have 105.
