Can u pls i’ll back i don’t want to ! : : [

It looks like the practice ones are all that matter so I'm only going to answer those. If you need the others answered let me know.

1. 5k-9=-3k+7

Add 9 to both sides: 5k-9+9=-3k+7+9

5k=-3k+16

Add 3k to both sides: 5k+3k=-3k+16+3k

(You are adding 3 and 9 instead of subtracting them because in the equation, they are negative numbers and you have to do the opposite operation to get rid of them.)

8k=16

Divide both sides by 8: 8k/8=16/8

k=2

2. 2(w-3)+5=3w-2

Use the distributive property: 2*w-2*3+5=3w-2

2w-6+5=3w-2

Combine like terms: 2w-1=3w-2

Add 1 to both sides: 2w-1+1=3w-2+1

2w=3w-1

Subtract 3w from both sides: 2w-3w=3w-1-3w

-w=-1

Divide both sides by -1: -w/-1=-1/-1

w=1

3. 8t+9=7t+6

Subtract 9 from both sides: 8t+9-9=7t+6-9

8t=7t-3

Subtract 7t from both sides: 8t-7t=7t-3-7t

t=-3
