Answer:

  • x=3

Step-by-step explanation:

[tex]\sf 14=-6+2\left(2x+4\right)[/tex]

[tex]\sf -6+2\left(2x+4\right)=14[/tex]

[tex]\sf -6+2\left(2x+4\right)+6=14+[/tex]

[tex]\sf 2\left(2x+4\right)=2[/tex]

[tex]\sf \frac{2\left(2x+4\right)}{2}=\frac{20}{2}[/tex]

[tex]\sf 2x+4=10[/tex]

[tex]\sf 2x+4-4=10-4[/tex]

[tex]\sf 2x=6[/tex]

[tex]\sf \frac{2x}{2}=\frac{6}{2}[/tex]

[tex]\sf x=3[/tex]
