a)33x + 135 = 26 * 9
33x + 135 = 234
33x = 234 - 135
33x = 99
x = 99 : 33
x = 3
Vậy x = 3
a) \(33x+135=26.9\)
\(33x+135=234\)
\(33x=234-135\)
\(33x=99\)
\(x=99:33\)
\(x=3\)
b) \(108.\left(x-43\right)=0\)
\(x-43=0:108\)
\(x-43=0\)
\(x=0+43\)
\(x=43\)
b)108 * ( x - 43 ) = 0
x - 43 = 0 : 108
x - 43 = 0
x = 0 + 43
x = 43
Vậy x = 43
Tìm số tự nhiên x biết:
A) 33x + 135 = 26 x 9
33x + 135 = 234
33x = 234 - 135
33x = 99
x = 99 : 33
x = 3
B) 108 x (x - 43) = 0
(x - 43) = 0 : 108
x - 43 = 0
x = 0 + 43
x = 43
