Answer 1

((((((ax 3/2) -1/3): 13/5) -1/4)x3)+7/4)= 2
(((((ax 3/2 ) -1/3 ) : 13/5 ) -1/4) x3) = 2- 7/4
(((((a x 3/2) - 1/3) : 13/5 )- 1/4 ) x3) = 8/4- 7/4
((((ax3/2) -1/3) :13/5)-1/4 )x3 =1/4
(((( ax3/2)-1/3) :13/5) -1/4)= 1/4:3
(((ax3/2 ) - 1/3) :13/5) -1/4= 1/12          ( 1/4 x1/3= 1/12)
((ax3/2)-1/3) :13/5 = 1/12 +1/4
((ax3/2)-1/3):13/5= 1/12+ 3/12
((ax3/2)-1/3) :13/5= 4/12 (simplific cu 4)
((ax3/2)-1/3): 13/5= 1/3
(ax3/2 )-1/3= 1/3 x 13/5
(ax3/2) -1/3= 13/15
ax3/2 =13/15 + 1/3
ax3/2= 13/15 + 5/15
ax3/2= 18/15 (simplific cu 3)
ax3/2= 6/5
a= 6/5: 3/2
a=6/5 x2/3
a= 4/5
