Question

How to solve -2x(-5)=3

Answer 1

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}`
