6. a 52 + x = 146-94
       52 + x = 52
       x = 52 - 52 
       x = 0
    
   b 2x + 35 = 121
      2x = 86
      2x = 43
   c  4, 75 x = 248 +  2, 75 x
       2x = 248
       x = 124

ex 6
a)52+x=146-94
52+x=52
x=52-52
x=0

b)2x+35=121
 2x=121-35
2x=86
x=86:2
x=43

c)4,75x=248+2,75x /-2,75x
2x=248
x=248:2
x=124

ex 7
a)
=371+92-(127-24)=
=463-103=
=360

b)
=1250000-(3251725-2627645)=
=1250000-624080=
=625920

c)240+x+135=452 /-135
240+x=317 /-240
x=77
