\(1\frac{1}{2}+x=\frac{3}{2}-7\)
\(\frac{3}{2}+x=\frac{-11}{2}\)
\(x=\frac{-11}{2}-\frac{3}{2}\)
\(x=\frac{-7}{1}\)
\(1\frac{1}{2}+x=\frac{3}{2}-7\)
=> \(\frac{3}{2}+x=\frac{3}{2}+\left(-7\right)\)
=> x = -7
Vậy x = -7
\(1\frac{1}{2}+x=\frac{3}{2}-7\)
\(\frac{3}{2}+x=\frac{-11}{2}\)
\(x=\frac{-11}{2}-\frac{3}{2}\)
\(x=\frac{-7}{1}\)
\(1\frac{1}{2}+x=\frac{3}{2}-7\)
=> \(\frac{3}{2}+x=\frac{3}{2}+\left(-7\right)\)
=> x = -7
Vậy x = -7
