Answer:

-3 is not a solution

Step-by-step explanation:

Subtstitute the possible solution into the equation and see if it is true

3x -5 = 4+2x

3(-3) -5 = 4+2(-3)

-9-5 = 4-6

-14 = -2

This is not true so -3 is not a solution

Answer:

  • No

Step-by-step explanation:

We will substitute 3 for the value of x in the equation.

[tex]{ \longrightarrow \sf \qquad 3x-5=4+2x }[/tex]

[tex]{ \longrightarrow \sf \qquad 3( - 3)-5=4+2( - 3) }[/tex]

[tex]{ \longrightarrow \sf \qquad - 9-5=4+( - 6) }[/tex]

[tex]{ \longrightarrow \sf \qquad -14=4 - 6}[/tex]

[tex]{ \longrightarrow \sf \qquad -14= - 2}[/tex]

We can see that,

[tex]{ \longrightarrow \sf \qquad L.H.S ≠ R.H.S}[/tex]

Therefore,

[tex]{ \longrightarrow \sf \qquad 3 \: is \: not \: a \: solution \:of \: equation \: ( 3x-5=4+2x) }[/tex]
