1. 1/5 = x - 9 / x

2. Cross multiply x = 5 (x - 9)

3. Distribute x = 5x - 45

4. Move the variable and change the sign x - 5x = -45

5. Add like terms -4x = -45

6. Divide x = 45 / 4

So the solution is x = 45 / 4 or 11.25

<span>Faster maid DATA:
time = x hr/job ; rate = 1/x job/jhr
Slower maid DATA:
time = 3x hr/job ; rate = 1/3x job/hr
Together DATA:
time = 3 hr/job ; rate = 1/3 job/hr
Equation:
rate + rate = together rate
1/x + 1/3x = 1/3
Multiply thru by 3x to get:
3 + 1 = x
x = 4 hrs (time for the faster maid to do the job)</span>
