Step-by-step explanation:
9/4x + 2 = 20
To get x by it's self you do the same on both sides of the = to cancel out each side.
9/4x + 2 = 20
(Multiply 9 on both sides)
4x + 2 = 20*9
(Now subtract 2 from both sides)
4x = 20*9 - 2
And finally divide both sides by 4
x = (20*9 - 2)/4
Then solve for x as normal.

Answer:
Each month you should save $ 150
Step-by-step explanation:
First, the earnings are given per year, so we need to transform $36000/year into dollars per month. So, using a rule of three as following, we obtain:
$ 36,000 ------------- 12 months
X -------------- 1 month
Solving for X, we get:

X = $ 3,000 /month
it means that earn $36,000/year is equivalent to earn $3,000/month
Now, we need to find the 5% of $3,000, this can be calculated making the following multiplication:

Then, each month you should save $150
