Well first all you have to do is simplifying both sides of the equation then of course isolating the variable then you should end up with

$n = \frac{29}{42}$

Hopefully this helps ^0^ Mark Brain

How do i solve this?

Answer:

$\large\boxed{x$

Step-by-step explanation:

$-\dfrac{1}{2}x+\dfrac{1}{3}>\dfrac{3}{5}\\\\\text{Find common denominator of the fractions}\\\\2,\ 3,\ 5\to2\cdot3\cdot5=30\\\\-\dfrac{1}{2}x+\dfrac{1}{3}>\dfrac{3}{5}\qquad\text{multiply both sides by 30}\\\\30\!\!\!\!\!\diagup^{15}\left(-\dfrac{1}{2\!\!\!\!\diagup_1}x\right)+30\!\!\!\!\!\diagup^{10}\left(\dfrac{1}{3\!\!\!\!\diagup_1}\right)>30\!\!\!\!\!\diagup^{6}\left(\dfrac{3}{5\!\!\!\!\diagup_1}\right)\\\\-15x+10>(6)(3)\\\\-15x+10>18\qquad\text{subtract 10 from both sides}$

$-15x>8\qquad\text{change the signs}\\\\15x$

Solving systems by elimination with multiplication: 8x+7y=20 and 4x-4y=-20

borishaifa [10]

If you put 0 in the place of x or y, which every one you choose, it will cancel it or and you can just divide the number next to it by the answer (-20, 20). Take it one step at a time, don't try to do both at the same time.

Find the value of x. <br><br> A. 6<br> B. 3<br> C. 5<br> D. 2

storchak [24]

$\\ \sf\longmapsto \dfrac{AK}{DK}=\dfrac{CK}{BK}$

$\\ \sf\longmapsto \dfrac{14}{12}=\dfrac{4x+1}{3x+3}$

$\\ \sf\longmapsto \dfrac{7}{6}=\dfrac{4x+1}{3x+3}$

$\\ \sf\longmapsto 7(3x+3)=6(4x+1)$

$\\ \sf\longmapsto 21x+21=24x+6$

$\\ \sf\longmapsto 24x-21x=21-6$

$\\ \sf\longmapsto 3x=15$

$\\ \sf\longmapsto x=\dfrac{15}{3}$

$\\ \sf\longmapsto x=5$

PLEASE HELP!! WILL GIVE BRAINLIEST

Colt1911 [192]

Answer:

-3

Step-by-step explanation:

Given the points, we can see that as x increases by 4, y decreases by 4, which means the slope is -1. Working backwards from (5, -8), we can decrease x by 5 (and thus increase y by 5, since we're subtracting a negative) and add that to -8 to find the y-intercept = -3
