Question

460+85,4=(x+200)×4.

Các bạn giúp mình nha.

Answer 1

460 + 85,4 = (x+200) * 4

545,4 = (x+200) * 4

136,35 = x+200

-63,65 = x

Answer 2

460+85,4=(x+200)x4<=>545,4=4x+800

=>4x=-254,6=>x=-63,65

^^

Answer 3

460+85,4=(x+200)x4

545,4=(x+200)x4

x+200=545,4:4

x+200=136,35

x=136,35-200

x=-63,65

Answer 4

<=> (x + 200) x 4 = 545,4

x + 200 = 545,4 : 4

x +  200 = 135,35

x = 136,35 - 200

x = -63,65

Answer 5

460 + 85,4 = ( x + 200 ) x 4

545,4 = ( x + 200 ) x 4

545,4 : 4 = x + 200

136,35 = x + 200

136,35 - 200 = x

-63,65 = x

Answer 6

460 + 85,4 = ( x + 200 ) x 4

545,4 = ( x + 200 ) x 4

545,4 : 4 = x + 200

136,35 = x + 200

136,35 - 200 = x

-63,65 = x

Answer 7

460 + 85,4 = ( x + 200 ) x 4

545,4 = ( x + 200 ) x 4

545,4 : 4 = x + 200

136,35 = x + 200

136,35 - 200 = x

-63,65 = x
