Answer:

[tex]x = 7.5[/tex]

Step-by-step explanation:

Isolate the variable, do this by first multiplying both sides by two

[tex]4x - 1 = 2(x + 7)[/tex]

[tex]4x - 1 = 2x + 14[/tex]

Subtract 2x from both sides of the equation

[tex]2x - 1 = 14[/tex]

Add one to both sides of the equation

[tex]2x = 15[/tex]

Divide both sides by 2

[tex]x = 7.5[/tex]
