Question

Tìm x biết: 2087-x:27=2015

                 45x(463+x)=44955

Answer 1

2087 - x :27 = 2015

x : 27 = 2087 - 2015

x : 27 = 72

x = 72 x 27

x = 1944

Answer 2

2087 - x : 27 = 2015

          x : 27 = 2087 - 2015

          x : 27 = 72

          x       =72 x 27

         x        =1944

 45 x ( 463 + x ) = 44955

          463 + x  = 44955 : 45

          463 + x = 999

                   x  = 999 - 463

                   x  = 536

Answer 3

2087-x:27=2015

        x:27=2087-2015

        x:27=72

        x    =72x27

        x    =1944

45x(463+x)=44955

       463+x=44955:45

       463+x=999

              x=999-463

              x=536

Answer 4

2087 - x : 27 = 2015

x : 27 = 2087 - 2015

x : 27 = 72

x = 72 x 27

x = 1944

45 x ( 463 + x ) = 44955

463 + x = 44955 : 45

463 + x = 999

x = 999 - 463

x = 536

Answer 5

2087 - x : 27 = 2015

x : 27 = 2087 - 2015

x : 27 = 72

x = 72 x 27

x = 1944

45 x ( 463 + x ) = 44955

463 + x = 44955 : 45

463 + x = 999

x = 999 - 463

x = 536

Answer 6

2087 - x : 27 = 2015

x : 27 = 2087 - 2015

x : 27 = 72

x = 72 x 27

x = 1944

45 x ( 463 + x ) = 44955

463 + x = 44955 : 45

463 + x = 999

x = 999 - 463

x = 536

Answer 7

2087 - x : 27 = 2015

x : 27 = 2087 - 2015

x : 27 = 72

x = 72 x 27

x = 1944

45 x ( 463 + x ) = 44955

463 + x = 44955 : 45

463 + x = 999

x = 999 - 463

x = 536
