Answer:

x = 11

Step-by-step explanation:

        Simplify [tex]2(x-3)+7[/tex]

        Apply the distributive property.

[tex]2x - 6 + 7= 23[/tex]

[tex]2x+1=23[/tex]

         Move all terms not containing  x  to the right side of the equation.

         Subtract  1  from both sides of the equation.

[tex]2x =23-1[/tex]

[tex]2x=22[/tex]

          Divide each term by  2  and simplify

[tex]\frac{2x}{2} = \frac{22}{2}[/tex]

          Cancel the common factor of  2

[tex]x = \frac{22}{2}[/tex]

          Divide 22 by 2

[tex]x = 11[/tex]

No 4 is not a solution of the equation becouse it would be an inproper solution

No... it’s not.

Let’s substitute x = 4 in a given equation

LHS = 2(x-3) + 7

= 2 (4-3) + 7 ( substituting x = 4)

= 2(1) + 7

= 2 + 7

= 9

RHS = 23

Here, as we can see by substituting x = 4, in the given equation, LHS ≠ RHS.

Hence, it’s not a correct solution
