Question

X + X x 2 + X x 3 = 1,23

tìm X

Answer 1

x+x*2+x*3=1.23

x*(1+2+3)=1.23

x*6=1.23

x=1.23/6

x=0.205

Answer 2

X + X * 2 + X * 3 = 1,23

=>x*(1+2+3)=1,23

=>x*6=1,23

=>x=1,23:6

=>x=0,205

Answer 3

x+x*2+x*3=1.23

x*(1+2+3)=1.23

x*6=1.23

x=1.23/6

x=0.205

k minh nhe

Answer 4

x + x x 2+ x x 3=1,23

x x (1+2+3)=1,23

x x 6=1,23

x=1,23:6

x=0,205

Answer 5

\(x+x\times2+x\times3=1,23\)

\(\Rightarrow x\times\left(1+2+3\right)=1,23\)

\(\Rightarrow x\times3=1,23\)

\(\Rightarrow x=0,205\)

Answer 6

Ta xét thấy khi X * 1 thì vẫn bằng chính nó.

Vậy ta có: x * ( 1 + 2 + 3 ) = 1,23

                x * 6 = 1,23

                x      = 1,23 : 6

                x      =   0,205

Vậy x = 0,205   

Answer 7

X + X × 2 + X × 3 = 1,23 X × 1 + X × 2 + X × 3 = 1,23 X × ( 1+2+3 ) = 1,23 X × 6 = 1,23 X = 1,23 : 6 X = 0,205
