Tìm X :(X+2138)*4= (2139-2076)*4
Tìm X biết (X+2139)*4=(2139-2076)*4
Không thực hiện phép tính, hãy tìm x:
(x + 2138) x 4 = (2076 + 2138) x 4
Không thực hiện phép tính tìm x :
(x+ 2138)× 4=(2076+2138)×4
Giúp mình vs, mình đang cần gấp
(x+2138)x4=(2076+2138)x4
Viết số thích hợp vào ô trống: 2138 x 9 = ... x 2138
Tìm x
A/ 4055 : x =5
B/ x : 6 = 2138
C/ 6384 - x = 498
tìm x biết x(x-4)+2(x-4)=0
Tìm x biết (14 x 14 - X -16 ) : 4 = 148 : 4
