Răspuns:

a) x+5×(33+128) = 895

x+5×161=895

x+805=895

x=895-805=90

b) x-53×(49–3.12)=996

x-53×45.88=996

x-2431.64=996

x=996+2431.64=3427.64

c) 53+2*x = x +111

2x-x=111-53

x=58

d) 23+5*x = 2 x +74

5x-2x=74-23

3x=51

x=51:3=17

e) 32+6*x=11*X-113

11x-6x= 113+32

5x=145

x=145:5=29

f) 8+13*x=2*x+41

13x-2x= 41-8

11x=33

x=33:11=3

Sper ca te-am ajutat!
