Question

Rezolvati inmultirea numerelor naturale ecuatiile:a)3*(x-2)+29=59
b)12*(x-5)+31=115
Va rooooooooooooooooooooooooooooooooooog am nevoie repede !!!!!!

Answer 1

a)3*(x-2)+29=59
3x-6+29=59
3x=59-23
3x=36
x=12

b)12*(x-5)+31=115
12x-60+31=115
12x=115+29
12x=144
x=12

Answer 2

3*(x-2) +29=59
x-2= (59-29 )÷3
x= 10+2
x=12

12*(x-5)+31=115
x-5= (115-31)÷12
x= 7+5
x=12
