Question

Please help me understand!!
Solve 4w − 7k = 28 for k. Show your work

Answer 1

@peachpi last one, I promise.. sorry :)

Answer 2

what do you have so far?

Answer 3

+4w to both sides, to get 32w on the right side? so 7k=32w?

Answer 4

4w is positive on the left side, so you need to subtract it.
When you subtract, 32 and 4w are not like terms, so they DO NOT COMBINE.

-7k = 32 - 4w

What comes next?

Answer 5

divide by -7? i mean 32 divided by -7

Answer 6

wait hold up. it was 28 on the right side, so

-7k = 28 - 4w

then yes, divide by -7

Answer 7

so k=-4-4w?

Answer 8

You have to divide the whole side by -7. Both of these are correct
