3(K-2)=15
How do I solve for K

k = 7

Step-by-step explanation: Start by distributing the 3 through the parentheses on the left side of the equation.

3(k) is 3k and 3(-2) is -6.

So we have 3k - 6 = 15.

Next, isolate the k term by adding 6 to both

sides of the equation and we get 3k = 21.  

Now divide both sides by 3 and k = 7.

If you want, you can check your answer by plugging a 7

back into the original equation to see if it works.

(-9) - (-4) = (-5) + (-10) =  -5= 16

6 - (-4) = (-1) - (-2) =

(-4) - (-2) = (-5) - (-6) =

(-4) - 10 = 9 - (-9) =

(-2) - 5 = (-2) + 5 =

(-2) - 7 = (-4) - (-10) =

(-8) + (-2) = 8 - (-2) =

(-9) + 10 = (-6) + 2 =

8 + (-10) = 31 - (-17) =

2 - (-10) = 87 - (-36) =

8 - (-2) = 20 - (-41) =

1 - (-7) = (-25) - 88 =

(-2) + 6 = (-56) + 91 =

(-4) - 4 = (-2) - (-56) =
