#3: 8x-2=4x+14
8x=4x+16 (add 2 on both sides)
2x=16 (divide 4 on both sides)
x=8 (divide 2 on both sides)
#4: 8 (solve number 3)
#5: 172(degrees)=180-8 (the whole line is 180 degrees and one angle is 8 degrees)
I'm not 100% sure on all of these i answered it late. I may have made a careless error (I am tired) but good luck!
