Question

please solve my question (iii),(iv),(v)

Answer 1

====================
2x+3(x-1)=5/2
2x+3x-3=5/2
5x=5/2+3
5x=5+6/2
5x=11/2
x=11/2/5
x=11/10
=====================
(2x-3/2) - (x+1/3)=(3x-8)/4
(3(2x-3)-2(x+1))/6=(3x-8)/4
((6x-9)-(2x-2))/6=(3x-8)/4
(4x-11)/6=(3x-8)/4
(4x-11)4=(3x-8)6
16x-44=18x-48
-44+48=18x-16x
4=2x
4/2=x
x=2
=====================
