Question

29,5 x ( x + 10,25 ) = 376,125                          748 : ( x - 31,72) = 13,6

Answer 1

29,5 x ( x + 10,25 ) = 376,125 

=> x + 10,25 = 376,125 : 29,5

=> x + 10,25 = 12,75

=> x = 12,75 - 10,25

=> x = 2,5

748 : ( x - 31,72) = 13,6

=> x - 31,72 = 748 : 13,6

=> x - 31,72 = 55

=> x = 55 + 31,72

=> x = 86,72

Answer 2

\(29,5\left(x+10,25\right)=376,125\)

\(29,5x+302,375=376,125\)

\(29,5x=376,125-302,375\)

\(29,5x=y\)(y tự tìm)

\(x=\frac{y}{29,5}\)
