She could do 1 chore in 38 hours. you could make an equation by doing 3/x=114
Given equation: -9-5(1-7y)=-20
Step 1) Distributing -5 over (1-7y), we get
-9 -5 +35y = -20.
Step 2) Now, combining like terms (-9-5 =-14) on left side, we get
-14 +35y = -20.
Step 3) Now, we need to get rid -14 form left side.
In order to get rid -14 from left side, we need to add 14 on both sides.
-14+14 +35y = -20+14
35y = -6.
Step 4) Dividing both sides by 35, we get
35y/35 = -6/35.
<h3>y = - 6/35.</h3>

Step-by-step explanation:
Please mark brainliest!
3/3 would be 1 hour
3/18 of the lawn would be done in 1 hour
18/3=6
6*1 = 6
it would take 6 hours to do the whole lawn
