try using the letter x for the variable, not the multiply operator.
Since all the choices are linear, check for the slope of the line.
as x increases by 1, y increases by 3. So, look for
y = 3x
Now, if x=0, 3x=0, but y is 3. So, we need to adjust things, leaving the 3x alone:
y = 3x+3

the ratio of the number of adults to children at a concert is 5:6. The ratio of the number of boys to the number of girls is 2:5. There are 36 more girls than boys at the concert. How many adults are there at the concert?

a/(b+g) = 5/6
b/g = 2/5
g = b+36
b/(b+36) = 2/5
b=24
so, g=60
a/84 = 5/6
a = 70
b/g = 2/5
g = b+36
b/(b+36) = 2/5
b=24
so, g=60
a/84 = 5/6
a = 70
