Question

a) 425+ x =146+94x
b) 12 x-23=121
c) 75x=248+74x

Answer 1

a) 94x - x = 425 -146
    93x = 279
       x = 3
b) 12x = 121 + 23
    12x = 144
       x = 12
c) 75x - 74x = 248
                x = 248 

Answer 2

a) 425+x = 146+94x 
separam termenii cu necunoscuta de  termenii liberi

     94 x -x = 425 -146

    93 x = 279

     x=279:93

       x = 3

b) 12 x = 121 + 23

    12 x = 144

       x = 12

c) 75x = 248 + 74x

  75x - 74x = 248

       x = 248
