5x-2=3x+8 must find what X is equal to

serious [3.7K]

I had homework on this today lol

First, add 2 to both sides. It would then be 5x = 3x + 10. Then subtract 3x from both sides and you would end up with 2x = 10. Divide 2x by 2 and the 10 by 2. The answer is x = 5.

Ainat [17]

Answer:

$\boxed{\sf x=\cfrac{1\pm \sqrt{-7} }{2}}$

Step-by-step explanation:

$\sf x^2-x+2=0$

Use quadratic formula:

$\boxed{\sf \frac{-b\pm \sqrt{b^2-4ac}}{2a}}$

$\sf a=1, b=-1, c=2$

___________________________

$\sf x_1,_2=\cfrac{-\left(-1\right)\pm \sqrt{\left(-1\right)^2-4\times \:1\times \:2}}{2\times \:1}$

$\sf \sqrt{\left(-1\right)^2-4\times \:1\times \:2}$

$\sf =\sqrt{-7}$

_________________

$\sf x_1,_2\cfrac{-\left(-1\right)\pm \sqrt{-7}}{2\times \:1}$

$\sf -(-1)=1$

$2\times 1=2$

$\sf x_1,_2=\cfrac{1\pm \sqrt{-7} }{2}$

What is the nearest thousand place for 3,429

muminat

If the place to the right of where you are rounding is 5 or higher, you have to round up. If it is 4 or lower, you have to round down. In the hundreds place, there is a 4. That's lower than 5 meaning that you round down/stay. So, the nearest thousands place is 3,000.
