\(2x+3-3.2x+1=32\)
\(2x.\left(1-3\right)=32-1-3\)
\(2x.\left(-2\right)=28\)
\(2x=-14\)
\(x=-7\)
Ta có: \(2x+3-3\cdot2\left(x+1\right)=32\)
\(\Leftrightarrow2x+3-6x-6=32\)
\(\Leftrightarrow-4x=35\)
\(\Rightarrow x=-\frac{35}{4}\)
\(2^{x+3}-3.2^{x+1}=32\)
\(2x.2^3-3.2^x.2=32\)
\(2^x.8-6.2^x=32\)
\(2^x.\left(8-6\right)=32\)
\(2^x.2=32\)
\(2^x=16\)
\(2^x=2^4\)
\(\Rightarrow x=4\)
\(2x+3-3\cdot2x+1=32\)
\(2x+3-6x+1=32\)
\(-4x+4=32\)
\(-4x=32-4\)
\(-4x=28\)
\(x=28:\left(-4\right)\)
\(x=-7\)
