Answer:

r = 3 1/3

Explanation:

Step 1: Simplify both sides of the equation.


  • 2(r-4)=-4(r-2)+4

  • (2)(r) + (2)(-4) = (-4)(r) + (-4)(-2) + 4

  • 2r - 8 = -4r + 8 + 4

  • 2r - 8 = -4r + 12

Step 2: Add 4r to both sides.


  • 2r - 8 + 4r = -4r + 12 + 4r

  • 6r - 8 = 12

Step 3: Add 8 to both sides.


  • 6r - 8 + 8 = 12 + 8

  • 6r = 20

Step 4: Divide both sides by 6.


  • (6r)/(6) = (20)/(6)

  • r = (10)/(3)

  • r = 3 (1)/(3)
