You would need to multiply the bottom equation by -2.5 (negative 2.5)
6x+5y=2
4x+2y=8
Multiply the bottom equation by -2.5:
-10x - 5y = -20
Now you can add the top equation to the new equation and it eliminates the Y variable:
6x + 5y = 2 +
-10x -5y = -20
Becomes:
-4x = -18
To find x, divide both sides by -4:
x = -18 / -4
x = 4.5

Answer:
da answer is C
Step-by-step explanation:
5(x+4)=4(x-6)
5x+5•4=4x-4•6
5x+20=4x-24
x= -44
Answer:
x - 2
Step-by-step explanation:
First, we know that the area of a triangle can be found using the formula: a = 1/2(bh).
We also know that the area of this triangle can be represented by (x^2-4).
Lastly, we know that one of the legs (let's call it the base) can be represented by (2x+4).
Let's plug in those values to the original formula: x^2 - 4 = 1/2(2x + 4)h
Now, let's solve for h!
We can multiply both sides by 2, then divide each side by (2x + 4) to isolate/solve for h.
If you need help on dividing polynomials, feel free to reach out!! I'd be happy to explain.
h = (x - 2)
