125 - ( x + 48 ) = 102
125 - ( x + 48 ) = 100
x + 48 = 125 - 100
x + 48 = 25
x = 25 - 48
x = -23
ukm ! ban giai minh cau dau tien nhaaa! minh se k cho ^^
29 x 87 - 29 x 23 + 64 x 71
48 x 19 + 48 x 115 + 134 x 52
27 x 121 - 87 x 27 + 73 x 34
125 x 98 - 125 x 46 - 52 x 25
136 x 23 + 136 x 17 - 40 x 36
làm nhanh nhanh lên hộ mình vs nhé, cảm ơn

giup mk nha mk tick cho
125 - ( x + 48 ) = 102
120 - x : 4 = 34 : 311

125 x 16 47 x 101
120 - x : 4 = 34 : 311
125 - ( x + 48 ) = 102
1+2+3+....+999=?
x^2.x^4.x^6.x^8....x^48...x^50=?
tìm X
5^x=125
3^2x=81
216 : x + 34 : x = 10
2125 : x - 125 : x = 100
