this is just going to make my brain hurt more if I do all of them
remember
1. you can do anything to an equation as long as yo do it to bothsides
try to isolate the variable
to add mixed fractions, just add the whole parts and then add or subtract the remaining fractions by making same denomenator
I will do first one and last one for showing how and the rest will be jsut answers with minimal work
29.
minus 3 and 3/7 both sides
k=7 and 4/5-3 and 3/7
k=7+4/5-3-3/7
k=7-3+4/5-3/7
common denomenator is 35
k=4+28/35-21/35
k=4+7/35
k=4+1/5
k=4 ad 1/5
30.
m=6-5+12/14-7/14
m=1+5/14
m=1 and 5/14
31.
j=9-4+2/3-1/9
j=5+6/9-1/9
j=5+5/9
j=5 and 5/9
32.
add 2 and 3/4 to both sides
x=4+1/5+2+3/4
x=4+2+1/5+3/4
x=6+4/20+15/20
x=6+19/20
x=6 and 19/20
33.
y=2+5/12+3+3/8
y=2+3+5/12+3/8
y=5+10/24+9/24
y=5+19/24
y=5 and 19/24
34.
add 3 and 1/3 to both sides
5+1/4+3+1/3=z
5+3+1/4+1/3=z
common denom is 12
5+3+3/12+4/12=z
8+7/12=z
8 and 7/12=z
z=8 and 7/12
