Answer:
Step-by-step explanation:
In this question we are given with an equation that is -5x - 10 = -20 . And we are asked to find it's solution ( value of x ).
Solution : -
[tex] \longmapsto \qquad \: - 5x - 10 = - 20[/tex]
Step 1 : Adding 10 to both sides :
[tex] \longmapsto \qquad \: - 5x - \cancel{10 }+ \cancel{10} = - \bold{20 }+ \bold{10}[/tex]
On further calculations , We get :
[tex] \longmapsto \qquad \: - 5x = - 10[/tex]
Step 2 : Dividing with -5 on both sides :
[tex] \longmapsto \qquad \: \dfrac{ \cancel{- 5}x}{ \cancel{- 5}} = \cancel{ \dfrac{ - 10}{ - 5} }[/tex]
On further calculations , we get :
[tex] \longmapsto \qquad \: \ \: \pink{\underline{ \boxed{\frak{x = 2}}}}[/tex]
Verifying : -
Now we're verifying our answer by substituting value of x in given equation. So ,
Therefore , our answer is correct .
