Answer:
(3,-4) or x=3 and y= -4
Step-by-step explanation:
I'm going to solve this by substitution
We first need to get a variable by itself in one of the two equations (it doesn't matter which variable and the equation you do the work on doesn't matter either)
I'm going to solve for y in the second equation
-4x-4y=4
add 4y and subtract 4 from both sides to get
-4x-4=4y
Divide by 4 to get
-x-1=y
We can plug this value in for y into the first equation and get
4x+5(-x-1)= -8
Solve for x
4x-5x-5= -8
-x-5= -8
-x= -3
x=3
We can plug this value into one of the first two equations and solve for y
4(3)+5y= -8
12+5y= -8
5y= -20
y= -4
Therefore the solution is (3,-4) or x=3 and y= -4

Answer:
(x+2)(x+5) or if you were looking for the x-intercepts they would be -5, and -2
Answer:
-20x-24
Step-by-step explanation:
To solve this equation, we can simply subtract like terms from left to right.
-4x-16x=-20x
Since we cant do anything with the -24, its stays the way it is.
The simplified equation is -20x-24
Hope this helps!
