Question

( 12×x+24):12-625:125=1

Answer 1

(12*x + 24)/ 12 - 625/125 = 1
(12*x + 24) /12 - 5 = 1
(12*x + 24) /12 = 5 + 1
12*x + 24 = 12 * 6
12*x = - 24 + 72
x = 48/12
x = 4

Answer 2

( 12×x+24):12-625:125=1
( 12×x+24):12-5=1
( 12×x+24):12=1+5
( 12×x+24):12=6
12×x+24=6×12
12×x+24=72
12×x=72-24
12×x=48
x=48:12
x=4
