Answer:
Add -4x to both sides--> 6x+9=4x-3 and 2x+9=-3
multiply both sides by -1/4 --> -4(5x+7)=-18 and 5x-7=4.5
multiply both sides by 1/4--> 12x+4=20x+24 and 3x+1=5x+6
multiply both sides by -4--> -5x/4=4 and 5x=-16
add -4 to both sides--> 8-10x=7+5x and 4-10x=3+5x
Answer:
The answer is 286.
Step-by-step explanation:
<u>13! can be rewritten</u> as 13*12*11*10!.
Since <u>10! is on the top and bottom of the fraction</u>, we can<em> eliminate them</em>. We are then left with 13*12*11/3!.
3! = 6. We can <u>eliminate the 6 from the denominator by diving the 12 by 6</u> in the numerator to get 13*11*2.
Finally, we can can evaluate the expression to get 286.

Answer:
4x^2+2x=10
Step-by-step explanation:
you need to add the ten to both sides to get it away, and then you can't do any thing to the 4x^2 or the 2x
