Answer:

3x/4-1/4(x-20)=x/4+32

3x/4-x/4+5=x/4+32

2x/4+5=x/4+32

2x/4-x/4=32-5

x/4=27

x=108

Answer:


(3x)/(4) - (1)/(4) (x - 20) = (x)/(4) + 32 \\ (3x)/(4) - (x)/(4) + 5 = (x)/(4) + 32 \\ (3x)/(4) - (x)/(4) - (x)/(4) = 32 - 5 \\ ((3x - x - x))/(4) = 27 \\ ((3x-2x))/(4)=27\\ (x)/(4) = 27 \\ x = 4 * 27 \\ \boxed{x = 108}

  • x = 108 is the right answer.
