Multiply bots sides by 9 so 4x+45 =9/2
4x= 9/2-90/2 = -81/2 and x= -81/8

(4x) / (9) + ( 5) = (1 / 2)

(4x)/(9) = (1/2) - 5
(4x)/(9) = (-9/2)
(4x) = (-9/2)*(9)
4x = -81/2
x = (-81/2) / 4
x = -81/8 OR same as -10 1/8

4x/9 +5 =1/2
4x/9=1/2- 5 or 4x/9= -4.5
4x=-4.5x9=-40.5
x=-40.5/4
x = -10.125 or -10 1/8

(4/9)x + 5 = 1/2
(4/9)x = - 9/2
x = -81/8 = -10.125
