Answer 1

b) x-15*3=996
x=1685
c) x=111-53
x=58
d)3x=51
x=17
e) -5x=-145
x=29
Nu am facut altceva decat sa mut termenii dintr-o parte in alta si sa fac calcule.

Answer 2

b)x-53•(49-3•12)=996
x-(2597-1908)=996
x-689=996
x=996+689
x=1685

c)53+2•x=x+11
53+2x=x+11
2x-x=11-53
x=-42



d)23+5•x=2•x+74
23+5x=2x+74
5x-2x=74-23
3x=51
x=51÷3
x=17

e)32+6•x=11•x-113
32+6x=11x-113
6x-11x=-113-32
-5x=-145
x=-145:5
x=-29
