Solve this k/3+4-2k=-9k
o-na [289]
K/3 + 4 -2k = -9k
First you add 9k to both sides
<span>k/3 + 4 -2k = -9k
</span>            +9k   +9k
<span>k/3 + 4 + 7k = 0
</span>
Now subtract 4 from both sides
k/3 + 4 + 7<span>k = 0
</span>        -4           -4
k/3 + 7<span>k = -4
</span>
Now multiply 3 by both sides
k/3 + 7<span>k = -4
</span>x3     x3    x3
k +21k = -12

Now add k + 21k
22k = -12

Now divide both sides by 22
<span>22k = -12
</span>-----    -----
 22      22
k = -6/11

Solve for y.
k0ka [10]

Answer:

y = \frac{2}{9}

Step-by-step explanation:

multiply \frac{2}{3} by \frac{3}{3} to get \frac{6}{9}:

\frac{6}{9} + y - \frac{1}{9} = \frac{7}{9}

simplify:

y + \frac{5}{9} = \frac{7}{9}

subract \frac{5}{9} from both sides:

y = \frac{2}{9}
