Answer 2

12 is 3 hours

Answer 3

8(e+5)=136
First divide over the eight
e+5=17
then bring over the 5
e=12

Answer 4

For 12, 20+4x=32 will be your equation.
20+4x=32
Bring over 20
4x=12
Divide by 4
x=3

Answer 5

Oh okay I read #12 wrong that one's easy lmao

Answer 6

For 13, your equation will be 40t=50t-80 (Where t is time in hours)
40t=50t-80
Bring over the 40t
0=10t-80
move 80 to the other side
80=10t
divide by 10
t=8
