Tìm x:
a) 541 + ( 218 - x ) = 735
b) 96 - 3 ( x + 1 ) + 42
c) [ 178 - ( 13x - 8 ) . 53 + 5724
d) ( x - 5 ) . ( x - 7 ) = 0
Tìm x biết
a)541 + (218 - x) = 735
A)541+(218-x)=735
541 + ( 218 -x) = 735
96 -3 X ( x + 1) = 42
5 X ( x +35) = 515
541 +(218-x)=735
541+(218-x)=735
541 + (218 – x) = 735
541 + ( 218 - x) = 735
541 + (218-x)=735
