j/8 +5K =30?

Question

SOLVE FOR J . NOT FOR K

Answer 1

j/8 + 5K = 30

subtract 5k for both sides
j/8 = 30 - 5K

multiply 8 for both sides
j = 240 - 40K

Answer 2

First move the 5K to the other side of the equation. You now have j/8 =30-5K
You can no express the equation as a proportion as follows:
j/8=30-5K/1
Cross multiply:
j x 1= (30-5K) x 8
j=8(30-5K)
j=240-40K
You need a value for K to get a final numercal value or another equation (parametric equations) in j and K

Answer 3

1 subtract 5K from both sides. the purpose of this is so that all terms that have a J in them will be on the same side of the equal sign. In this case there is only one such term so what you have to do is easy.
2. multiply each side by 8.

1. J/8 + 5K - 5K = 30 - 5K and J/8 = 30 - 5K
2. (J/8)*8 = (30 - 5K)*8 and J = 240 - 40K

Answer 4

j / 8 + 5k = 30

Subtracting 5k from both sides, you get
j / 8 + 5k - 5k = 30 -5k
j / 8 = 30 - 5k

Multiplying both sides by 8, you get
(j / 8) x 8 = (30 - 5k) x 8
j = 240 - 40k

Answer 5

to solve for j
first- multiply each by 8
8 x j/8= j 5k x 8=40k 30 x 8=240
that gives you j + 40k= 240

then- subtract 40k from both sides
that gives you your answer of
j=240 - 40k

Answer 6

j/8 +5K =30
j/8 + 5K - 5K = 30 - 5K
j/8 = 30 - 5k
j = 8 (30 - 5K) = 240 - 40K

Answer 7

J = 8(30-5K)
J = 240 - 40K

Answer 8

j/8 + 5k = 30
j/8 = 30 - 5k
j = 8(30 - 5k)
- In the above step multiply 8 with both sides...

Answer 9

add -5k to both sides

J/8= 30 -3k

multiply both sides by 8
J= 240 - 24k

Answer 10

j/8+5k=30
j+5k=30x8
=240

j=240-5k

5k=240-j

k=48-j
