<h3>Solution:</h3>
-38d - 57 = -19d + 76
or, -38d + 19d = 76 + 57
or, -19d = 133
or, d = 133/-19 = -7
<h2>Answer: d = -7</h2>
<h3>To Check:</h3>
By putting the value of d, we get
-38(-7) - 57 ≥ -19(-7) + 76
or, 266 - 57 ≥ 133 + 76
or, 209 ≥ 209
Hence, Verified.

<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>
