2/3-3k/4=71/12?

Answer 1

"2/3-3k/4=71/12"

2/3=8/12

"8/12-3k/4=71/12"
8/12-3k/4-(8/12)=71/12-(8/12)
-3k/4=63/12
-3k/4(*4)=63/12(*4)
-3k=63/3
-3k=21
k=-7

Hope that helps your understanding.

Answer 2

2/3 - 71/12 = 3k/4
8/12 - 71/12 = 3k/4
-63/12 =3k/4
(-63/12)/(3/4) = k
-63/12 * 4/3 = k
cross multiply -63 and 3 =
cross multiply 12 and 4 =
-21/3 * 1/1 = k
-21/3 =k
-7 = k
k = -7

Answer 3

x-5/8=7/8 x=7/8 + 5/8 [you are able to circulate words from one area of the equation to the different as lengthy as you adjust the sign x=12/8 = 3/2 [comparable denominator so in basic terms upload numerators] 2/3+3k/4+seventy one/12 i bypass to think of the 2d + sign is somewhat an = sign 2/3 +3k/4 = seventy one/12 3k/4 =seventy one/12-2/3 = seventy one/12 -8/12 = sixty 3/12 3k = 4(sixty 3/12) = sixty 3/3 =21 ok = 7 a/2+one million/5=17 a/2 = 17-one million/5 = sixteen 4/5 a = 2(sixteen 4/5) = 32 8/5 = 33 3/5 9y/14+3/7=9/14 9y/14 = 9/14 -3/7 = 9/14 - 6/14 = 3/14 9y = 14(3/14) = 3 y= 3/9 = one million/3

Answer 4

I assume that you would like to solve for k.

Subtract 2/3 from both sides to get:

-3k/4 = 71/12 - 2/3

2/3 is equal to 8/12, so you get:

-3k/4 = (71-8)/12

which is

-3k/4 = 63/12

Now multiply both sides by 4

-3k = 4*63/12

whichi s

-3k = 252/12

And divide both sides by -3 to get

k = -252/(12*3)

Which is

k = -252/36

Which reduces to:

k = -7

Answer 5

3k/4 = 71/12 - 2/3 = 63/12 = 21/4

So, 3k = 21 or k=7

Answer 6

2/3-3k/4=71/12 multiply each term by 12
8-9k=71
-9k=63
k=-7

Answer 7

k = -7

Answer 8

try turning that into english then people will answer

Answer 9

k=ok
