Answer 1

2x+1/3-(x-5)=3/2,x=?
2x+1/3-x+5=3/2
x=3/2-1/3-5=9/6-2/6-5=7/6-30/6=-23/6
16x-40=9x+16 ,x=?
16x-9x=16+40=56
7x=56
x=8
2(3-x)=-4(x+5),x=?
6-2x=-4x-20
2x=-26
x=-13
2x-10.3x=15 ,x=?
-8.3x=15
x=-150/83
0.52x-(1-0.52)x=80 ,x=?
0.52x-0.48x=80
0.04x=80
x=2000
x/2+3x/2=7,x=?
(x+3x)/2=7
4x/2=7
2x=7
x=7/2
3x+7=32-2x,x=?
3x+2x=32-7=25
5x=25
x=5
3x+5(138-x)=540 ,x=?
3x+690-5x=540
2x=150
x=75
3x-7(x-1)=3-2(x+3),x=?
3x-7x+7=3-2x-6
2x=1
x=1/2
3[4(5y-1)-8]6=,x=?.
