Bài 1 :
x + 678=2813 X x 23 = 3082 4529+x=7685 36 x X = 27612
x = 2813 - 678 X = 3082:23 x = 7685-4529 X = 27612 : 36
x = 2135 X = 134 x =3156 X = 767
x - 358 = 4768 x : 42 = 938 2495 - x = 698 4080 : x =24
x = 4768+358 x = 938x 42 x = 2495 - 698 x = 4080:24
x = 5126 x = 39396 x = 1797 x = 170
Bài 2 :
a) x + 6734 = 3478+5782 b) 2054 + x = 4725 - 279 c ) x -3254 = 237x145 d) 124 - x = 44658 : 54
x +6734 = 9260 2054+x = 4446 x - 3254 = 34365 ( Sai đề )
x = 9260-6734 x = 4446-2054 x = 34365+3254
x = 2526 x =2392 x = 37619
