Question

Can somebody please help me with this question??10=10(k-9)

Answer 1

answer:

k = 10

step-by-step explanation:

objective: get k by itself on one side of the equal sign

1. distribute the 10 to (k - 9) by multiplying these values by the outside value

10 × k = 10k

10 × -9 = -90

new equation: 10 = 10k - 90

2. get rid of 90 by doing the opposite (so we add 90) and what we do on one side we do to the other

(10k - 90) + 90 = 10k (90 cancels out)

10 + 90 = 100

new equation: 100 = 10k

3. get k by itself by dividing by 10 - since 10 is being multiplied by we need to get rid of it by doing its opposite (division) and doing this on both sides

10k ÷ 10 = k (the 10 cancels out)

100 ÷ 10 = 10

new equation: 10 = k

is k by itself? yes so k is equal to 10

Answer 2

K = 10

I think. I’m not positive sure though. Hope this helped!
