a,\(32-x=-78\)
\(\Leftrightarrow x=32-\left(-78\right)\)
\(\Leftrightarrow x=110\)
b,\(12+x=-37\)
\(\Leftrightarrow x=-37-12\)
\(\Leftrightarrow-49\)
c,\(-63-x=-18\)
\(\Leftrightarrow x=-63-\left(-18\right)\)
\(\Leftrightarrow x=-45\)
d,\(35-75-x=15\)
\(\Leftrightarrow-40-x=15\)
\(\Leftrightarrow x=-40-15\)
\(\Leftrightarrow x=-55\)
e,\(63-x=-37\)
\(\Leftrightarrow x=63-\left(-37\right)\)
\(\Leftrightarrow x=100\)
