235 - 135. ( 2x - 31) = 100
135 . (2x - 31) = 135

235-135 x (2x-31)=100
135 x (2x-31)=100
2x-31=100/135-20/27
2x=20/27+31=\(31\frac{20}{27}\)

=>135*(2x-31)=235-100

135 x ( 2x - 31 ) = 135
2x - 31 = 135 : 135
2x - 31 = 1
=> 2x = 1 + 31 = 32
x = 32 : 2 = 16
\(135\left(2x-31\right)=235-100\)
\(135\left(2x-31\right)=135\)
\(2x-31=1\)
\(2x=1+31=32\)
\(2=32:2=16\)
