 Tìm \(x\)

(8 x 18 - 5 x 18 - 18 x 3) x X + 2 x \(x\) = 8 x 7 + 24

Trà lời các bước tìm \(x\)cho mình nhé(ai đúng mình tick-_-)

Answer 1

(8 x 18 - 5 x 18 - 18 x 3)x + 2x = 8 x 7 + 24

<=> [18 x (8 - 5 - 3)]x + 2x =   80

<=> 2x = 80

<=> x = 40,k nhé bạn

Answer 2

(8x18-5x18-18x3)xX+2xX=8x7+24

=>8x(8-5-3)xX+2xX=80

=>8x0xX+2xX=80

=>0+2xX=80

=>X=80:2

=>X=40

Answer 3

(8 * 18 - 5 * 18 - 18 * 3) * X + 2 * x = 8 * 7 + 24

[ 18 * (8-5-3)]                 * x + 2 * x =   56 + 24

18 * 0                             * x + 2 * x=      80

      0                               * x + 2 * x   = 80

                              x *( 2+0)             = 80

                             x *   2                   = 80

                             x                          = 80 : 2

                             x                          = 40

Answer 4

\(\left(8\times18-5\times18-18\times3\right)\times x+2\times x=8\times7+24\)

\(\Rightarrow18\times\left(8-5-3\right)\times x+2\times x=56+24\)

\(\Rightarrow18\times\left(3-3\right)\times x+2\times x=80\)

\(\Rightarrow18\times0\times x+2\times x=80\)

\(\Rightarrow0\times x+2\times x=80\)

\(\Rightarrow0+2\times x=80\)

\(\Rightarrow2\times x=80\)

\(\Rightarrow x=80:2\)

\(\Rightarrow x=40\).

Answer 5

40 nha

Answer 6

\(\left(8\times18-5\times18-18\times3\right)\)\(\times x+2\times x=8\times7+24\)

\(\left[18\times\left(8-5-3\right)\right]\)\(\times x+2\times x=56+24\)

\(18\times0\)\(\times x+2\times x=80\)

\(0\times x+2\times x=80\)

\(2x=80\)

\(x=40\)

Vậy \(x=40\)
