a) 541+ ( 218 - x ) = 735
218 - x = 735 - 541
218 - x = 194
x= 218 - 194
x= 24
b) 12 . x - 33 = 32 . 33
12 . x - 33 = 9 . 27
12 . x - 33 = 243
12 . x = 243 + 33
12 . x = 276
x = 276 : 12
x = 23
c) 231 - ( x-6 ) = 1339 : 13
231 - ( x- 6) = 103
x- 6 = 231- 103
x-6 = 128
x= 128 + 6
x = 134

\(12x=243+33\)
\(12x=276\)
\(x=23\)
\(c,231-\left(x-6\right)=1339:13\)
\(x-6=231-103\)
\(x-6=128\)
\(x=134\)
\(d,2.x-138=2^3.3^2\)
\(2x-138=72\)
\(2x=72+138\)
\(2x=210\)
\(x=105\)
\(e,2^x.4=128\)
\(2^x=128:4\)
