3r-6=-21
3r-6+6=-21+6 (Add 6 to both sides...)
3r=-15
r=-5
3r-6=21
3r-6+6=21+6 (Add 6 to both sides...)
3r=27
r=9

Q=2p+1
subsitute 2p+1 for q in other eqaution
4p+2q=8
4p+2(2p+1)=8
4p+4p+2=8
8p+2=8
minus 2 both sides
8p=6
divide both sides by 8
p=6/8
p=3/4
sub back
q=2p+1
q=2(3/4)+1
q=6/4+1
q=3/2+1
q=3/2+2/2
q=5/2
p=3/4
q=5/2
It’s 27. 58 and 5/12 rounds down to 58, 30 and 5/7 rounds up to 31. 58-31= 27
