(2x-5)/4 +( 5x+9)/2=5/4
(2x-5 + 10x+18)/4=5/4
(12x + 13)/4 = 5/4
(12x + 13)/4 * 4 = 5
12x + 13 =5
12x =5-13
12x= -8
x = -8/12
x = -2/3
hope u got the answer and the way to do it

Qu a million 5x - 3x = 60 2x = 60 x = 30 Qu 2 i do no longer trust this question and picture that it will probable study as :- x/4 - 9/2 = ( x + 6 ) / 2 x - 18 = 2x + 12 - 30 = x Qu 3 again i do no longer trust ! 2/t = t / ( 5t - 12 ) 10t - 24 = t ² t ² - 10t + 24 = 0 ( t - 6 ) ( t - 4 ) = 0 t = 4 , t = 6 playstation Sorry for being this variety of cynic yet I`ve considered it too commonly !

(2x-5)/4 + (5x+9)/2 = 5/4 --> multiply by 4 to get rid of the denominator
(2x-5) + 2(5x +9) = 5
2x - 5 + 10 x + 18 = 5
12x = -8
x = -8/12 = -2/3

(2x-5)/4 + (10x+18)/4 = 5/4
denominator 4 cancels out
2x-5+10x+18=5
12x+13=5
x=-8/12
x=-2/3

(2x-5)/4 +(5x+9)/2 = 5/4?
LCD
[(2x-5)+2(5x+9)]/4 = 5/4
[ 2x-5 + 10x + 18]/4 = 5/4
[12x +13]/4 = 5/4
12x +13 = 5
12x = -8
x = -8/12
x = -2/3
