Question

Tìm x biết:

180-(x-45):2=120

Answer 1

\(180-\left(x-45\right):2=120\)

\(\Rightarrow\left(x-45\right):2=180-120=60\)

\(\Rightarrow x-45=60\times2=120\)

\(\Rightarrow x=120+45=165\)

Vậy x= 165

Answer 2

=> (x - 45) : 2 = 180 - 120 = 60

=> x - 45 = 60 x 2 = 120

=> x = 120 + 45 = 165

Answer 3

180-(x-45)=120:2

180-(x-45)=60

       x-45=180-60

       x-45=120

       x    =120+45

       x    =165
