Answer:

No Solution

Step-by-step explanation:

[tex]4x-5=2\left(2x+1\right)[/tex]

Expand:

[tex]4x-5=2* \:2x+2* \:1[/tex]

[tex]4x-5=4x+2[/tex]

Add 5 to both sides:

[tex]4x-5+5=4x+2+5[/tex]

[tex]4x=4x+7[/tex]

Subtract 4x from both sides:

[tex]4x-4x=4x+7-4x[/tex]

[tex]0=7[/tex]

No solution as this is false.
