What led new england farm girls to resign from working in the mills and return to their family farms in the 1840s?

In the 1840s, New England farm girls resigned from working in the mills and return to their family farms because they fear of losing their jobs and their boarding houses became overloaded so the rental fee was costly and it didn't offer worthy foodstuff and home materials. Their wages also are even if they work longer hours.

step-by-step explanation:

look at the x and y axis

8 - (2a + 7) = a + 40     distribute/multiply - into (2a + 7)

8 - 2a - 7 = a + 40

1 - 2a = a + 40       add 2a on both sides

1 = 3a + 40         subtract 40 on both sides

-39 = 3a       divide 3 on both sides

-13 = a

[proof]

8 - (2a + 7) = a + 40

8 - (2(-13) + 7) = -13 + 40

8 - (-26 + 7) = 27

8 - (-19) = 27

8 + 19 = 27

27 = 27
