\(\dfrac{x}{3}-\dfrac{1}{2}=\dfrac{1}{5}\)
\(\dfrac{x}{3}=\dfrac{1}{5}+\dfrac{1}{2}\)
\(\dfrac{x}{3}=\dfrac{7}{10}\)
\(10x=21\)
\(x=2,1\)
/ -2 / = 2x + 3
\(=>2=2x+3\)
\(=>-1=2x\)
\(=>-2x=1\)
\(=>x=\frac{-1}{2}\)

-12.(x-5)+7.(3-x)=5
-12x-60+21-7x=5
(-12x-7x)-(60+21)=5
-19x-81=5
-19x=5-81
-19x=-76
x=-76:(-19)
x=4
x=
x=44:(-19)
\(-12\left(x-5\right)+7\left(3-x\right)=5\)
\(60-12x+21-7x=5\)
\(81-19x=5\)
\(19x=81-5\)
\(19x=76\)
\(x=4\)
