3x+4y=10

subtract 3x from both sides

4y=-3x+10

then divide 4 for on both sides, including the -3x and 10

then you should get y=-3/4x + 10/4

simplify

y=-3/4x + 5/2 

your final answer should be f(x) -3/4x + 5/2

the answer to life, the universe and everything

is 42

first find out how many kilometers simon can do in 1 minute

15km per 60min

divide  15/60 you find out that he goes .25 km per 1 minute

then you find out how many times .25 goes into 11 km divide 11/.25

.25 goes into 11, 44 times so it takes simon 44 minutes

i hope its correct :)
