If each person paints at the same rate, then the amount of work
the group accomplishes in any period of time is directly proportional
to the number of workers in the group.

If you decrease the number of workers, then the amount of work
they do in the same amount of time decreases by the same factor.

If 10 people do one whole job in 5 days, then 70% of that number
of people will do 70% of a whole job in 5 days.

Solve the equation. –x 8 3x = x – 6 x = –18 x = –14 x = 2 x = 4
LenKa [72]

The value of the variable x in the equation –x + 8 + 3x = x – 6 is - 14.

<h3>How to find variable in an equation?</h3>

The variables of an equation can be found as follows:

–x + 8 + 3x = x – 6

The variable in the equation is x.

Therefore,

–x + 8 + 3x = x – 6

combine like terms on the left side

-x + 3x + 8 = x - 6

2x + 8 = x - 6

subtract x form both sides of the equation

2x - x + 8 = - 6

x + 8 = -6

subtract 8 from both sides

x = -6 - 8

x = - 14
