X= -8
Step 1. You have to distribute -5 through the parentheses and you will get -5x-35=3x+ 29
Step 2. Move variable to the left-hand side and change its sign and get -5x-3x- 35= 29 Part 2. Move constant to the right-hand side and change its sign -5x-3x=29+35
Step 3. Collect the like terms -8x=29+35
Part 2. Add the numbers -8x=64
Step 4. Divide both side of the equation by -8

gtnhenbr [62]

Answer:

28 minutes spent in washing the dishes.

Step-by-step explanation:

Given the table

Chore             time in minutes

Sweeping           42

Dishes                  ?

Amanda spent a total of 70 minutes competing her chores this week

Total of 70 minutes spent

42 minutes spent in sweeping . to find the number of minutes Amanda spent in washing the dishes , subtract 42 minutes from the total time spent

let x be the number of minutes spent washing the dishes

42+x=70

To solve for x , subtract 42 from both sides

42+x=70\\x= 70-42\\x=28

28 minutes spent in washing the dishes.
