Question

Afla valoarea lui X
1) (42+32)+X=98
2) X+(73-49)=51
3) X-(43-11)=26
DAU COROANA! MULȚUMESC!

Answer 1

1)  ( 42 + 32 )  + X = 98
      74 + X = 98
       X = 98 - 74
       X = 24

2) X + ( 73 - 49 ) = 51
    X + 24 = 51
    X = 51 - 24
    X = 27

3) X - ( 43 - 11 ) = 26
    X - 32 = 26 
    X = 26 + 32 
    X = 58

Answer 2

(42+32)+x=98
x=42+32
x=74
x=98-74
x=24 solutia ={24}

x+(73-49)=51
x=73-49=24
x=51-24=27

x-(43-11)=26
x=43-11=32
x=32+26=58
