The first one is 5x-15=2x+12+3x 5x-2x-3x=12+15 0=27
The second one is 6.5x-7.75x=-12+14.5 -1.25x=-2.5 Divide both sides by - 1.25 X=. 02
The third one is K-10=3 K=13 The second part of the third one is -|k-10|=3 -k+10=3 -k=3+10 -k=13 Divide both sides by negative K=-13
The fourth one is 4n+32=56 4n=56-32 4n=24 Divide both sides by 4 N=6 The second part to that one is -4|n+8|=56 -4n-32=56 -4n=88 Divide both sides by - 4 N=22
The fifth one is N+7-6=8 N=8-7+6 N=1+6 N=7 The second part to this one is -|n+7|-6=8 -n-7-6=8 -n=8+7+6 -n=21 Divide both sides by negative N=-21
The last one is 5x-7-3=9 5x=9+7+3 5x=19 Divide both sides by 5 X=19 over 5 The second part to this one is -|5x-7|-3=9 -5x+7-3=9 -5x=9-7+3 -5x=5 Divide both sides by - 5 X=-1 I hope this helps you out.
