3x−82=x−6
solve with correct answer

x = 38

Step-by-step explanation:

3x−82=x−6   (subtract x from both sides)

3x−82 - x= −6    

2x - 82 = -6 (add 82 to both sides)

2x -82 + 82 = -6 + 82

2x = 76  (divide both sides by 2)

x = 76/2

x = 38

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
