Having problems with this question help needed

Answer 1

• No

Explanation:

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

`{ \longrightarrow \sf \qquad 3x-5=4+2x }`

`{ \longrightarrow \sf \qquad 3( - 3)-5=4+2( - 3) }`

`{ \longrightarrow \sf \qquad - 9-5=4+( - 6) }`

`{ \longrightarrow \sf \qquad -14=4 - 6}`

`{ \longrightarrow \sf \qquad -14= - 2}`

We can see that,

`{ \longrightarrow \sf \qquad L.H.S ≠ R.H.S}`

Therefore,

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

Answer 2

-3 is not a solution

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
