Step one =

-3/4x + 25 -1/8x = 1/8x = 1/8x -3 - 1/8x

-7/8x + 25 = -3

Step two =

-7/8x + 25 - 25 = -3 - 25

-7/8x = -28

Step three =

(8/-7) * (-7/8x) = (8/-7) * (-28)

Answer:

x = 32

Step-by-step explanation:

(-3/4)x + 25 = (1/8)x - 3

Subtract 25 from both sides:

(-3/4)x + 25 - 25 = (1/8)x - 3 - 25

(-3/4)x = (1/8)x - 28

Subtract (1/8)x from both sides:

(-3/4)x - (1/8)x = (1/8)x - 28 - (1/8)x

(-7/8)x = -28

Multiply both sides by 8:

8(-7/8)x = 8(-28)

-7x = -224

Divide both sides by -7:

-7x/-7 = -224/-7

x = 32

Radda [10]

Answer:

It takes 32 Minutes for 12 people to paint 12 walls

Step-by-step explanation:

If it takes 8 people 32 minutes to paint 8 walls, then that means each person takes 32 minutes to paint 1 wall. With that being said, If you have 12 people painting 12 walls, It will take 32 minutes for all 12 walls to be painted.

elena-14-01-66 [18.8K]
Y-2x=6 => y=6+2x
Y+2x=0
(6+2x) + 2x = 0
6 + 4x = 0
4x= 6
X=6/4
X= 3/2
Y=6+2x
Y=6+2. 3/2
Y= 6 + 3
Y=9
Check: y-2x=6
9-2. 3/2 = 6
9 - 3 = 6
