6, 7, 8, 9
Step-by-step explanation:
There ya go. The numbers of possible amounts of mangos he could buy without exceeding his budget.
X - (9x - 10) + 11 = 12x + 3(-2x +

) equals
x = 
.
First, simplify brackets. / Your problem should look like: x - 9x + 10 + 11 = 12x + 3(-2x +

).
Second, simplify x - 9x + 10 + 11 to -8x + 10 + 11. / Your problem should look like: -8x + 10 + 11 = 12x + 3(-2x +

).
Third, simplify -8x + 10 + 11 to -8x + 21. / Your problem should look like: -8x + 21 = 12x + 3(-2x +

).
Fourth, expand. / Your problem should look like: -8x + 21 = 12x - 6x + 1.
Fifth, simplify 12x - 6x + 1 to 6x + 1./ Your problem should look like: -8x + 21 = 6x + 1.
Sixth, add 8x to both sides. / Your problem should look like: 21 = 6x + 1 + 8x.
Seventh, simplify 6x + 1 + 8x to 14x + 1. / Your problem should look like: 21 = 14x + 1.
Eighth, subtract 1 from both sides. / Your problem should look like: 21 - 1 = 14x.
Ninth, simplify 21 - 1 to 20. / Your problem should look like: 20 = 14x.
Tenth, divide both sides by 14. / Your problem should look like:

= x.
Eleventh, simplify

to

. / Your problem should look like:

= x.
Twelfth, switch sides. / Your problem should look like: x =

which is your answer.
<h3>
Answer: 6 hours</h3>
Work Shown:
(90 lawns)/(45 hours) = (12 lawns)/(x hours)
90/45 = 12/x
2 = 12/x
2x = 12
x = 12/2
x = 6
It takes 6 hours to mow 12 lawns.
