a) 66
b) 68
c ) 17
d) 3
ai thấy đúng thì k mình nhé
a)541+(218-x)=735
218-x=735-541
218-x=194
x=218-194
x=24
b)5.(x+335)=515
x+335=515:5
x+335=103
x=103-335
x=-232
c)96-3(x+1)=42
3(x+1)=96-42
3(x+1)=54
x+1=54:3
x+1=18
x=18-1
x=17
d)12x-33=3^2.3^3
12x-33=3^5
12x-33=243
12x=243+33
12x=276
x=276:12
x=23
\(541+\left(218-x\right)=735\)
\(218-x=735-541\)
\(218-x=194\)
\(x=218-194\)
\(x=24\)
a) 541 + ( 218 - x ) = 735
218 - x = 735 - 541
218 - x = 194
x = 218 - 194
x = 24
24
