Question

4600÷[10×(x-10)+10]=10rezolvare prin metoda mersului invers

Answer 1

4,600 ÷ [ 10 × ( x - 10 ) + 10 ] = 10
[ 10 × ( x - 10 ) ] = 4,600 ÷ 10
10 × ( x - 10 ) = 460
x - 10 = 460 ÷ 10
x - 10 = 46
x = 10 + 46
x = 56.

Answer 2

4,600 : [ 10 x ( x - 10 ) + 10 ] = 10
[ 10 × ( x + 10 ) + 10 ] = 4,600 : 10
10 × ( x + 10 ) + 10 = 460
10 × ( x + 10 ) = 460 - 10
10 × ( x + 10 ) = 450
x + 10 = 450 : 10
x + 10 = 45
x = 45 - 10
x = 35.
