Solve this for eleventeen hours of good luck (this is from a challenge problem its not graded)

[covert karma]

ok so we will call the number of bushes in garden A to be a and garden B as b

so we know that
a=b+9
and a+3 = 1.5(b-3)

we now have 2 variables and 2 equations

meaning that we can solve for one of the variables

It’s just solving a linear system of two variables given two equations

Do u mean eleven

[stiff linden]

I'd say substituting the the way a is defined in the first equation into the second equation is the best way
