3/10

Step-by-step explanation:
-2x(-5)\text{ = 3}

Multiplication of same sign gives positive number. Multiplication of opposite signs give negative number.


\begin{gathered} -2*-5\text{ = 10} \\ -2x*-5\text{ = 10x} \end{gathered}
\begin{gathered} 10x\text{ = 3} \\ \text{divide both sides by coefficient of x} \\ \text{coefficient of x = 10} \\ (10x)/(10)=(3)/(10) \end{gathered}
x\text{ = 3/10}
