Can you show me how to do this one?
(3x / 4 + 2) = (5 - x / 3)
I tried a lot of times but it's always been wrong

(3x/4=(3/4)x and x/3 =(1/3)x)
(3/4)x+(1/3)x=5-2
(seperate variables and numbers)
(9/12)x+(4/12)x=3
(find LCD)
(13/12)x=3
x=3 * (12/13)
(invert fraction)
x =36/13

(3x/4) + (8/4) = (15/3) - (x/3)
(3x+8)/4 = (15-x)/3
Cross Multiply :
3(3x+8) = 4(15-x)
9x + 24 = 60 - 4x
13x = 36
ANSWER : x = 36/13

3x+8)/4 = 15-x)/3
9x+24=60-4x
13x=36
x=36/13

a million) 5/4x=3/2+a million ==> 5/4x - 3/2x =a million ==>10/8x - 12/8x =a million ==> -2/8x=a million ==> -a million/4x=a million ==> -x=4 ==> x= -4 2) a million/x+a million=a million/x+2 ==> x+a million=x+2 ==> x - x = 3 which isn't plausible because x - x =0 , putting forward x - x = 3 is like putting forward 0=3 so this equation has no answer, as for the third equation , look at answer on real i guess it truly is a properly answer

3x/4+2=5-x/3
3x/4+x/3=5-2
9x/12+4x/12=3
13x/12=3
13x=36
x=36/13
